An American Builder Builds a Racer and it’s an amazing piece, the MotoCzysz C1! Michael Czysz has a running prototype that’s getting coverage in the motorcycle press and it deserves a lot of attention. An inline 4, mounted longitudinally usually has a lot of torque transferred to the bike, so Czysz split the four into a pair of twins then reversed the front pair so it counter-rotates and offset them for a 15 degree V configuration. And that’s just for starters, the single sided front fork, the gearbox under the engine, rear springs separate from the shock, it just goes on and on. His ambitious goal is to race MotoGP. Potential street versions down the road, too.

Yo Mike, cool bike! I have an idea for a design mod. Re: page 43 Jan ’05 CYCLE WORLD. Why not rotate the brake caliper forward about 80 degrees and incorporate it into the swingarm itself and then move the whole thing to the other side and use the sproket for the brake rotor? This would eliminate the unsprung weight of the bracket and the brake rotor. This is an idea I came up with years ago and keep expecting to see it used by some sportbike builder. I have actually seen the design in use. I once acquired a B&S powered minibike that used a cable operated puck which in turn used the center of the sproket for the braking surface. It was about the only part of the machine that really worked well. Anyway I just thought I’d bounce this off you. I’m not an engineer, just a retired log truck driver and motorcycle nut. It probably isn’t a patentable idea as it has been used before, but who knows? I just thought it would be really cool if you could use it on your extremely inovative machine. Talk about bragging rights! If you’d like to kick this around or more likely, point out the flaw in my thinking, please feel free to e-mail me or call me at 541-396-4092. Sincerely, Jan Curran

the problem with that is the caliper ahs a major effect upon the stability of the bike and slinging it in front of the sprocket throws the rear end up in the air once the brake is on
by mounting it low the rear will squat under braking
the only way to do that with the sprocket is to make the caliper wide enough to go around the chain and then it may well be too
heavy to be of any advantage
also dont forget the effect chain lub has upon a brake pad
moto gp boys really rely on the rear brake for a lot of things other than braking
ive seen rossi exiting a corner at full throttle and holding it back with the rear brake
so any change in performance could prove detrimemtal

Hello Everyone,
I am hoping somebody in the www can direct me to a company that sells sportbike kits. I have built two bikes with GSXR frames and had them titled under my initials. Howver I am no genius nor a solid mechanic so as you might guess the problems never end. They look great and perform well sometimes I used mostly after market parts for perfomance and some mods I created.
I really want a kit that with the purchase comes tech support.
I ve spent enough money on these two bike that I could have bought a 999. So if a company does exsist someone that visits here is my best chance.
