Yeah I gotta dig myself out of some debt before even considering a bike again. I do have a basket case 2002 KX250 that I am finally piecing back together though, so I'll keep that for awhile I guess.

In other news, I'm going to try and retrofit ABS to the Brammo. Can't ever have too many projects!

Oi Z3n, you're a smart dude. Can I retrofit ABS to my 690SMC? Mine is a 2008.

Shimrod posted:Oi Z3n, you're a smart dude. Can I retrofit ABS to my 690SMC? Mine is a 2008. Z3n uses effort post! Ok, so, ABS: There are 2 major companies that do ABS - Bosch and Continental. There's a mix across manufacturers, my 1290/early BMWs use Bosch, and the S1000XR / new BMWs use the Continental system. Bosch is the long standing player in the field, with Continental a relative newcomer, working primarily with BMW for now, and is an advance IMU/cornering type system. ABS systems come in a couple of configurations. The simplest ones are essentially piggyback systems - they accept power/brake functionality from the bike, have a couple of independent hall effect sensors that go from the ABS unit to the wheel speed sensors - these systems are pretty common across the board, and typically fitted to budget bikes and such - nearly all early ABS systems were of this form - wheel speed sensors only. It's important to think of these systems as "matched sets", though, as the ABS control unit is integrated on to the pump, and is pre-programmed for the number of cutouts on the reluctor ring. They're also going to be optimized to a particular wheel size, and there's likely some rate of change stuff in there that's determined by the overall weight and dimensions of the bike. But ultimately, these are relatively simple systems that do nothing but make sure that if rate of change at the wheels exceeds a certain fixed value, the ABS engages, and doesn't release until the wheel starts spinning again. These systems are likely to be pretty easy to retrofit. Then there's the more complex systems that rely on the IMU/gyro setups, more complex relationships between the ECU, road speed, braking force, etc, etc, etc. Those systems are, for now, out of the bounds of reasonable retrofitting, as you're talking about spoofing a bunch of additional, arbitrary data, like proprietary implementations of ECU communications, blah blah blah. The ideal for retrofitting is: Matched to your wheel sizes, matched roughly to your motorcycle's expected braking performance/weight, ECU independent, cheap, and widely available, with the ABS sensors and reluctor rings as independent components from the braking system/wiring harness. The more modern you can get on the hardware, as well, the better - I'm broadly assuming that there are improvements in sampling rates, internal models for wheel rate of change, etc, etc. For the Brammo, in interests of keeping prices reasonable, we're going with a Ninja 650 system, which fits almost all of the ideals - the only one it doesn't is the reluctor rings are riveted to the rotors. The total cost for raw parts thus far is around $360 bucks from eBay - I expect all in, pricing will be around $600 if I don't have to get custom reluctors made, if I do, well, probably closer to $800. Most of the remaining cost is going to be in custom lines - Venhill is my new favorite company, because they do swivel fitting custom lines, with any banjo bend available in a wide variety of colors for $45 a line. A huge part of the pain in the rear end of setups like this is figuring out the routing of your brake lines / angles and such, so being able to fit those things makes like SIGNIFICANTLY easier. Bleeding a custom system like this will be a bit of a pain in the rear end, but it shouldn't be too bad. There's also some minor concerns around packaging and such, the ABS pump is about the size of your fist, and needs to be mounted somewhere where you can run lines from the master cylinders to the ABS pump and back to the calipers. So now that I haven't answered your question at all: Retrofitting ABS to a 690 would be interesting. I think the biggest problems you'd run into would be that the bike is relatively light weight, and might be able to cause a greater rate of wheel speed change than the ABS system would expect under normal usage. You're also unlikely to be able to fit a system that supports supermoto mode/no rear ABS without some pretty significant work. But - I'd bet you could easily fit a Ninja 650 system to the bike. Throw a switch on it to disable it when you want to back it in or ride like an idiot, and it'd let you add in the safety margin during normal commuting for sure. The crazier option would be to pick up a complete setup off a 690 Duke ABS, and fit the entire wiring harness/electrical system to the 690, piggyback fueling on it to match the SMC engine tuning, but I think that'd probably run you quite a bit of money/work unless you were going to find a crashed 690 Duke ABS and part out the rest of it to fund your ABS swap. Because I've already done the work and may as well save someone else the trouble: Ninja 650 Wiring Harness / ABS Connector posted:Black & White - Front wheel speed sensor The Brammo has the fittings for additional fuses and such, so I'm hoping that I can wiring everything as if it the system were OEM. The open questions for me at the moment are as follows: There's 2 types of fused power, an ignition lead, and a line that taps into the brake line. I'm unsure of what the brake line tap does - if the ABS system only engages when the brake light is on (which makes sense - you don't want the system engaging if the brakes aren't being used), that would make an easy bypass for hooligan configuration - just have a switch on that line that cuts the connection to the brake lights. The ABS system will probably lose its mind at that point if you lock the tires, but it should be easily fixable by a power cycle. I'm hoping when all of this is said and done, it'll be clear and simple enough that I can essentially make a "kit" for other bikes, as being able to spend 500 bucks to add ABS to bikes would be pretty fantastic (for example, on the CBX).

Hmm, interesting. So finding a trashed smc-r with abs and swapping it over isn't quite that straight forward.

You could do that was well but a wrecked SMC-R is super hard to come by in my area.

Really love the idea of retrofitting the ABS. The Brammo is too good of a bike to let sit... And it's such a practical idea! I'm not used to thinking that about your projects.

Fixed for SoCal, although I doubt it's that much different anywhere in the US. I've been regularly searching craigslist for any 690 variants in my area for 4+ years now and have yet to see an R. Only one I've ever come across was randomly parked in the lot at work.

As far as retrofitting ABS goes, how do you get sensor rings on a bike that's never had them? Mill slots into the ends of the rotors and mount hall effect sensors there? My friend desperately wants ABS on his 1964 BMW R50, and I kept telling him it's nigh impossible, but your posts give me hope.

Plan is to just CAD up some stuff and get it water jet /plasma / laser cut from a plate of steel. Anything else is excessive and complicated, that solution is cheap and easy. On the Brammo I'll need to do it on the sprocket side for the rear wheel. Problem Id see with doing the swap on an old BMW is you need hydraulic brakes front and rear, and a reliable 12v system. If those things are available, then it's totally doable. I'd measure the wheels and try and find an abs system that uses similar wheel sizes but you could probably get away with faking it by adjusting the number of slots to take into account the difference in wheel sizes from a 17 inch setup. It wouldn't be an absolutely perfect setup but the primary function here is to insta-release on a locked brake so it should be still better than human. Would need testing.

builds character posted:Can you please explain why that particular fix and how it worked? Also, just how fast were you going when you hit that rock? I'm just the builder for that bike, the owner was riding it at the time. He hit a square edged concrete bridge corner that had been exposed from use - probably about 4 inches tall - at around 40mph. Instantly deflated the tire, and bent both sides of the rim. We spent some time hammering the wheel back into some semblance of shape, which knocked it off the bead. At this point, I went off to snag the recovery vehicle. They continued working on it, resetting the bead with gasoline, then they packed the remaining gap with tire plugs - which sealed, but without positive pressure, as the tire rotated, the plugs themselves didn't have enough strength to hold. So a curved stick, bailing wired to the wheel, provided enough positive pressure that the tire plugs sealed against the edge of the stick and it was rideable, slowly. They were limping it out and I ended up meeting them while they were rolling out. That was, of course, the second bent rim incident - the first one was fixed by just using a hammer and block of wood to straighten the rim enough that it only had a slow leak. Apparently, superduke rims aren't made for offroad use. Who could have guessed! Z3n fucked around with this message at 17:39 on May 24, 2016 |

Ok, I've got a couple minutes to hammer out a thing here from my phone, and the go ahead to start breaking cover, so here's the the sneak peek of what I've been working on - the KTM 1290 SM-R. KTM parts are basically motorcycle Legos, and about a year ago I did the initial research on this but lacked the need to make this bike. As it turns out, a buddy was selling his 1290 racebike and I managed to find another buddy who wanted me to do the build, so off we went. The mod list looks roughly like this: 950 SM forks (200mm of travel) Aftermarket brake lines to fit + Suzuki brake line distributor Harley Davidson fork brace, drilled to mount 950SM fender Machined out some prototype rearset relocators that allow for fitment of OEM 1190 Adventure R pegs. OEM Duke 690 bar 1290 super adventure header, cut down 90mm to fit OEM SuperDuke exhaust 1190 adventure r shock 1190 skid plate Plus a few other odds and ends in the process After that point (pre exhaust cutting) the bike looked like this: And of course, how to better break it in than to fit TKC80s: Test ride it: And then send it off to the sheetiron 300, an off-road rally of 300 miles in Northern California: And that is how you got the story above. There's a video coming out soon detailing the Sheetiron 300 testing event - I'll post it up when it comes out. And I'll have a longer post here covering the full build, but until then, you'll have to content yourself with this preview. Oh, and in 2 weeks it goes to the track for the first time. Refit Q3s and off we go.

So here's the crazy thing - this was a screaming deal on a SuperDuke but I think the full cost of the build is less than +3k on the cost of the base SuperDuke. This is all in, less than a new SuperDuke would have cost him.
