Oops. I let my friend who's never been on a bike on my little 125cc china bike and now he's about to sign on a CBR600RR. Please don't die my man.

Somewhere a few pages back someone mentioned how handling on a real sports bike kinda doesn't give a lot of signals back to the rider. It's muted. I kinda get that. I sorta regurgitated that back to my friend.

He's really stuck on the idea of buying one bike and keeping it forever. It's his choice I guess.

I've been riding about 15 years now and my brain still does that. I've thought recently I'd like a track bike, and instead of just getting an SV650 as any rational person would, I'm thinking I'd like a VFR400 or an RS125 or something.

I mean, you can get to your personal idea of a perfect bike and own it forever. Lots of people do.

It just requires riding a lot of different bikes to understand what you do and don’t like.

The idea that you can just randomly pick your perfect bike based off, I guess looks? as a new rider is crazy

Pardon my ignorance!! but why is an RS125 a bad track bike? Yes, it's a 2-stroke GP bike, so it's going to be a bit of a handful compared to an SV650, but does that make it bad? I am under the impression they are fairly inexpensive, unlike a VFR400. I personally wouldn't track a +10k bike.

RS wouldn't be bad, but they're not exactly easy to find. A running SV is on every street corner across the US for a reasonable price, though. RS would be a bit extreme in its ergos and power delivery, too, when it would make more sense to get a friendly bike.

A buddy of mine had an rs125 for a track bike and it was really, REALLY good in a razor thin margin of every possible thing coming together in a perfect storm.

If you were in the middle of the tiny powerband, set up perfectly for a corner, had the tires up to temp, nailed your shifts perfectly to keep it on the boil, completely committed 100%, and the air temperature was right for its jetting, it would take down bikes much more powerful than itself.

Mess up any of that, however and it wasn’t going anywhere.

He wound up getting rid of it and tracking a *horn fanfare* SV650 instead after the RS seized on track.

Not a cop
I spent probably three hours trying to adjust my chain slack/alignment with everything that could probably go wrong happening (massive over-/under-adjustments, not having the right size/depth sockets, constantly second-guessing the chain alignment tool, and just being generally out-of-shape) but dammit I pulled it off. I'm still not super happy about the alignment tool I used and will probably get a set of calipers to measure from the back of the adjustment nut to the end of the bolt and square it up between the left and right sides.

I did have a question for the more experienced people here. When I was loosening up the axel nut from one side the other side would start turning, so I wrenched one side in place and loosened the other. However, when I reversed the process to tighten up to the suggested torque, the wrench would immediately start clicking on the second side that I would start tightening. Is that normal or should there be any cause for concern?

Sorry if that was oddly explained, but I'm very old, tired, and paranoid about messing up something on baby's first wrench job.

Toe Rag

yeah that alignment tool is worthless and no different than just closing one eye and looking at the chain straight on from the rear. A caliper is the way to go IMO and what I'll use if I think I messed it up somehow. I too completely overestimated how many turns of the nut were necessary to tighten the chain. It turns out 2 full turns is way too much!

I would get a set of combo wrenches because there's a lot of places on a motorcycle you'll have a hard time getting a socket. I just replaced my gear shift lever the other day and there is no way any one of those nuts could be touched with a socket.

As to your second question I am definitely a mechanical simpleton but you should only be tightening the axle on one side. For example, you would put a wrench on the bolt head side of 5 just to keep it from spinning and then tighten 7.

Ok there are two semi related issues I'll try to tackle seperately here:

1. Chain tension stuff

As toe rag says, alignment tools are worthless tat. There are many time-honored alignment methods, old people seem to like the string method you can google while younger folk like measuring with calipers as above.

Or, you can release yourself from the trappings of empirical reality and forget about measuring anything and do this instead: loosen the adjusters off until the axle can slide all the way forward and do that. While holding the wheel forward either with your meat or with a block of wood, depending on your setup, tighten the axle nut just enough that the wheel can't slide anywhere by itself. Run the adjuster bolts in until they touch. At this point the axle nut needs to be just tight enough to provide some dragging resistance for the adjuster bolts to pull on, sometimes finger tight is enough to do this, other times you need a spanner. Now you just turn the adjuster bolts equally, simply by counting the turns! Put your spanner/ratchet at the 12'o'clock position and tighten to 6 or fully over to 12 (or whatever fraction is repeatable and easily referenced), do the same on the other side. As long as you count the turns consistently and evenly this method will work to perfection because it relies on the consistency of the adjuster threads, which is far more accurate than squinting at a vernier. Eventually, you'll get to the range where the chain starts to tension. Absolutely critical: do not obtain the chain tension you want by loosening the adjusters. It is a one-way operation and if you try to loosen things off everything will be aligned like poo poo, so if you overtighten the chain and have to loosen the adjusters, you need to loosen them both evenly a couple of turns and approch it again with both adjusters tensioned. Spin the wheel and find the tight spot in the chain by grabbing the bottom run at mid-length, it may take a bunch of turns to repeat but you'll find it, that's where you set your tension. Work the adjuster bolts backwards until it's set right, tighten axle, then give the adjuster bolts a tiny bit of extra tension so they don't work loose from any slight loosening as you did the nut up. FWIW a quarter-turn on the extremely common 1.25mm adjuster bolt thread equates to 0.31mm so you can adjust to an extremely fine degree this way.

2. Axle stuff

You need to hold the bolt end of the axle still with a spanner or socket and bar, and tighten the nut gradually until you get the click/beep. Again this is a one-way operation, you can't loosen your way to the right tension so if you over-do it, loosen and start again. Don't loosen the axle right off or you'll destroy all your effort in following the instructions above, half-way will do so you can smoothly ramp the torque into the wrench again. Make sure the axle nut/bolt head and the flats they press on are nice and clean, grease the axle bolt with a light layer of bearing grease so it doesn't corrode in there.

I’m so spoiled by axle snails. I haven’t actually checked axle alignment in years now, and when I set chain tension I grab it and wiggle it up and down and say “Yeah, that looks right.”

Spent 4 hours riding today (~180 miles) with a mix of divided highway, county two lane twisties with what must have been 50 years of patches on it and interstate. Wind came to play too and I was riding away from a monsoon off in the distance. Had a couple pucker moments with wind gusts, which must have been 25mph or so.

My instinct is to slow down, which did help, but I feel like I should speed up as faster = more stable. What's the right thing to do here?

Loosen your arms until they're noodles of mince, look as far ahead as possible, ignore everything the bike does. The safest thing is to do nothing because anything you do will make the bike react and change geometry, which changes your line and makes you react, which makes the bike react, which...

The safest and best way is to be in full command of the throttle and brakes so any small movements due to wind or bumps are overridden by the far larger forces of front-rear loading.

So, this may be obvious to most, but had completely gone over my head when I first started and I guess I didn't pay too much attention to it when I bought my bike as everything felt 'new' anyway...but..

In trying to improve my general bike handling I've started paying more attention to how I'm sitting, etc and as I started experimenting with trail braking, I realized I couldn't. There was no way for me to grab the brake and maintain any kind of throttle control.
This in turn made me look at my control setup and I've now adjusted more or less to the way he does here and things are much better:

Definitely slow down. If I'm doing 90mph and the wind makes me go from 0 degrees straight ahead to 15 degrees to the right, and it takes me a half second to correct the issue, I will have gone farther towards the next lane over if I'm doing 90mph than had I been doing 65mph. At least that's my theory for why I slow down when you get crazy wind (it's actually because it feels a lot better so who cares why). I also didn't find my bike drastically increased in how stable it felt once you got past something like 15 - 25mph, but I did ride a friend's FZ-07 once for ~50 miles and I was surprised at the effort it took to turn at freeway speeds compared to the streets, so maybe there's something to that.

I can't really think of a bike safety situation that's improved by going faster. Given the choice between braking and accelerating to get out of danger, braking at least significantly lowers the forces you feel in any crash compared to speeding up.

I just passed my riding exam this morning. I was super nervous but managed well enough to pass anyway. So now I'm licenced to ride all by myself without the yellow vest of shame, which feels pretty great. My very generous brother will let me ride his versys 650 for the time being, but I need to get my own ride come spring at the latest. Hopefully used bike prices will drop significantly when the weather turns bad like they usually do from what I've heard.

What people have said but also: steady throttle is the safest. If you're on a shut throttle you have no front suspension and all the weight is on the front tyre, not a good place to be over rough terrain. On a steady throttle you have maximum suspension travel front and rear, most of the weight is on the back tyre, steering effort is drastically reduced.

Naturally the safest method is to wheelie over them at speed.

Reminder that motorcycles exhibit positive stability (when in motion) and, when all rider torques are removed, they will attempt to right themselves and go in a straight line.

(mute, lovely music)
https://www.youtube.com/watch?v=C0_d-SjyTgY

The video above is all racing motorcycles, so your street bike is even more stable than those. On lovely roads, metal grille bridges, etc the best thing to do is loosen up your grip and let the bike sort itself out. It might wiggle underneath you but it wants to stabilize and keep moving forwards.

In a heavy crosswind you will probably find that you have to lean into it a bit to make the bike track a straight line, but again, the vehicle will be more stable the fewer inputs you provide.

After doing 210km/h on the autobahn, i can fully believe that story. The wind is intense. When i got my head out of tuck when looking at my blind spots (remember, the average family sedan can reach 200km/h just fine, they might just have crept up on you) the wind really snapped it backwards. Got a sore neck the next day!

I did kinda enjoy the feeling of the various bubbles of air that exist on the road. Lorries have this thick wall of air you bust through if you fly past them. Overtake a row of them and you're spending not a second completely upright, instead constantly re-balancing for the varying crosswinds and air bubbles. Things start to look a bit like cockpit footage of an airplane on final approach, constantly making little bank angle adjustments.

Also bloody weird that i have to put in a bit of effort to overtake modern Sprinter or Transporter vans. Christ, they've gotten fast. I wouldn't exactly call my SV650 slow...

It was the most visceral riding experience ever. From the intense reactions of the bike on the wind and pressure waves from the lorries, to the high pitched roar of the engine, to the heat bubbles rising into the fairing, to the intense radiant heat from the exhaust that's even noticeable with a hurricane force air blast cooling them down. God i need to do that again. Every force imaginable you can feel with your body.

Keep in mind, the average speed on the autobahn is barely above 100km/h and people WILL overtake and not see you coming because you're a dot in the mirror approaching way faster than people expect. Drive responsibly.

Since I managed to get my licence with one single vacation day left I spend most of today in the saddle (with breaks obvs). I rode in heavy traffic, twisties, highway, gravel roads that were sometimes more like trails - pretty much anything and everything. Good times were had. It's liberating not to have an instructor right behind you and inside your helmet over the radio.

I reflected more than once that the education I've received is good and comprehensive, and the only times anything felt at all out of control was when I disregarded what I've been taught. "Remember your training" is probably the main thing I'll try to keep in mind going forward so I don't pick up any bad habits from here on. Despite said training I nearly dropped the bike when I attempted a tight U-turn in first gear and had no power available when I needed it since I was actually in neutral.

I also got rained on a bunch at the end but I had brought rain gear which worked fine. Even the boots and gloves held up which was a pleasant surprise. The only issue was a bit of fogging at low speed with the visor fully closed.

I also learned that I really, really like earplugs on the highway but not so much on slower sections. Best to protect my hearing regardless I guess.

I was like not sure if I should ask this here or in the discussion thread or questions thread. I am still like a new rider and it's kind of a safety question.

Mechanically, is there any kind of way a bike can fail and like throw you off or get you hurt easy? Like - in a way that makes a bike inherently higher risk than a car? They seem pretty basic mechanically and thus not a lot of crazy ways to fail - most of it would be entirely user error - is that a bad assumption?


My friend, not a new rider, was pulling wheelies and riding his CBR500r aggressively in a parking lot. Mid wheelie his rear tire locked and he skidded out.
He was able to maintain control of the bike and stopped it. It was a little scary to see.


The noise it made was awful, sounded like automatic gunfire. To me it sounded like a chain force sliding over a sprocket or maybe a gear slipping.

He said he didn't downshift and drop the clutch. The bike also has a slipper clutch. It would have made retarded Yoshi noises if he did that. Woulda heard it.

His engine didn't like seize did it? I can't think of what the hell else can cause a bike to do that.
