the CC is just calculation of silinder formula, nothing new
circle surface (pi X j square) x height = volume of silinder

CC (centi cubic) is measurement unit (centi X centi= 10 power 2 X 10 power 2)
if not wrong...

gear box, gear ratio is complex, take almost 1 day to understand...

alexei already come out with the simulation just download it and key the gears u 1 the, and the speed will come out....

11k RPM = racing compression 14:1 + CAM profile and spring.
Service interval = Every 200km.

Added on June 13, 2011, 3:11 pmIn the excel file, you can play with the parameters and see see the bike performance. I'm not rocket scientist, but I think the spec and real world performance of the bike quite accurate. Give it a try and share here.

Stock bike peak hp is at 8500 RPM. Depending on riding habit, you can change peak RPM to 6k for city riding.

Bro, Sorry maybe miscommunication,not saying ur spreadshet....

I m saying with stock things, is the uncut CDI can go until 11k rpm? Need so high compression ar?

Just where this bike can go with stock stuff tats all....

And how much faster did it become?
PS - guys, how much is a battlax tyre? my rear Michelin is done (after 1 year and 6000km)
I thought of trying out the 120 Pirelli front tyre from my RS125 (mechs said it was possible, butI think I'll just let it pass)
*
the price range between rm250-rm400..
pirelli size 120? sure can fit lc rim.. but the opening is not good..
