I keep chiming in on other people's "my ATE brakes suck" threads about what a great improvement the handlebar mounted MC has been. A few people have asked what I did to implement it, so here we go. I used a 13mm Magura MC, which I bought from Economy Cycle, where I get all my parts for my RD350. It cost about $110 and I like the look of it, though someday I'll get a more attractive pinch bolt for it. I had an extra lever perch/ throttle and chopped off the lever perch portion of it. The middle picture shows the least flattering angle of the surgery, but in real life you'd never notice what had happened. With this removed, the /5 style throttle and the new MC nestled together as if it were meant to be, and all that remained was to come up with a brake line to make it all go together. I ended up using a put-it-together yourself brake line out of parts offered by Goodridge. BMW uses what I think is called an inverted bubble flare, which I found unavailable in Goodridge's line of fittings, so I had a local garage make a new hard line( the one that goes from the caliper up to the top of the fork slider) with a BMW style inverted bubble on the caliper end, and an inverted conventional flare on the other to mate with the end of the new braided line. It was a real frustrating pain in the ass involving a lot of running around, but I live in an area very poor in speed shops and the like. I imagine that if that were not the case, I could have easily had something made up to suit. Anyhow the results were worth the trouble, as the brakes are much better than before. I wouldn't say that they are up to the best that modern bikes have to offer, but their limits are better than mine. In normal stops, two fingers are plenty, and the feel is good. I think all told, I spent $160 or so. I hope this will help someone else. I'd think that if you wanted to do this on a dual-disk front end, you might want to get a MC with a bigger piston, I think the stock one is 16 or 17mm. I feel that it's a good thing to go a small step down in piston size, as it makes the braking action happen over a longer range of lever travel, giving lower effort and better modulation. Now get to work everyone!
