questions

[OB_Konrad]

I have been thinking about
how to increase roll-on and
not being one to go much over
150 swapping sprockets.
I know folks have gone to a 16
tooth front, but some enineers
feel that lowering front sprocket size
markedly increases chain and sprocket wear,
increases frictional loss and chain noise.
Is there any problem in going up 2 or 3
teeth on the rear sprocket ?
Also, has anyone seen the Perimeter Braking
System by Braking USA?

I tried 4 and 5 teeth in the rear talk about a wheelie machine.and i thought my H-2 was bad. I went back to stock.
Note: 2 up in rear feels real good around town and nobody beat me in a roll-on.

johnny cheese with 2 up in the rear does it get to wheele prone in first gear?

 

[OB_Johnnycheese]

Heck it's wheelie pron in first
so I would say yes.
remember you do have to control that grip on the end of the handlebars

Konrad: I saw the perimeter braking system, and it looks like nothing else in the world. However, I didn't like the 4-piston calipers. I don't know if the increased diameter of the rotors has anything to do with less clamping force needed, but my common sense says no. It will undoubtedly reduce heat, therefore fade though. I don't even want to think how much it costs, but I would like to see a busa fitted with one.

Is this the one that the rotor is like on the outer part of the rim
If so I saw something about them 5 years ago on some show.it stated that smaller pads and calipers would be used due to the stopping power is increased due to it is easier to stop something the further you are from the axle center.It sounded better how they put it.

I went to the site that was linked to Labusas.
IT IS THE SAME THAT I SAW
It should stop the same if not faster than stock but I think you have to change wheels
$$$$$$$$$$$$$$$
Mine seems to stop fine.I would try steelbraided lines before investing a ton of money

RAM - Race Applications Monaco, has been promoting the perimeter braking setup for a while now, there site is http://www.ram.mc

In simple terms the reason these brakes offer improvement is that they offer more leverage on the rotating wheel, same theory as 320mm vs 300mm rotors.

This is the same company who makes the single sided swingarms for the Hayabusa.

The quality of their products is top rate to say the least, I have imported several of their sssarms for the Hayabusa and these bikes will be finished soon as we finish up with the Ohlins fork conversions. We did not use the perimeter braking, PFM's are now mounted on the front with Brembos in the back.

I went down 1 tooth in the front and at the same time up 3 in the rear. I also installed a new chain and set the axle back as far as I could go.

I wanted a bike that could keep up with R1's down low, and still have plenty up top. This combo was just a bit excessive (constant wheel spin and front wheel in the air), so I went back to a 17th tooth front.

Again you can see this on my Busa Mods page.
