t1000

Sry for the late reply

was stuck with college, assignments, and hostel :P

We input required was at which rpm peak hp is produced, and wats max rpm that engine can rev to, Gear ratios for each gear, final gear ratio (i got hold of a 4wheeler gear calc), tyre size (including rim/wheel dia)

I cant seem to find the url of the site from which i got hold of that calc, but the other ones which are available, are pretty much the same.

About getting hold of the ratios, Now all thats left for me is opening up a scrap p220s gearbox Or have the patience to sit through my bike's gearbox servicing.

hi there.

Your post in P220 dtsi thread caught my eye.
where you posted this.

gear no. ------- RPMx1000 ------- speed (kmph)
-- 1 -------------- 1 ----------------- 4
-- 2 -------------- 1 ----------------- 7
-- 3 -------------- 1 ----------------- 10
-- 4 -------------- 1 ----------------- 13
-- 5 -------------- 1 ----------------- 15.5

Ive been searching for the P220 gear ratios. If you could share them(less work for me ), it would be helpful primary and secondary ratios included.

And how did you get those figures?

I got use a gear calc, Some program that a random guy made.
I got almost similiar results with the 2nd 3rd 4th 5th cogs of a R15
Our 1st gear is shorter I suppose
