will update more in first post if found and confirmed!!

u can cross check them and verify them too; i'll update accordingly!!

G.K.

final reduction = (rear sprocket teeth/front sprocket teeth)

reduce no of teeth at front or increase teeth at rear = acceleration[lowend]

increase no of teeth at front or reduce teeth at rear = speed [topend]

its all rite but what does it means about 1st ,2nd,3rd 4th or 5 th gear ratio.....? HOw Gear ratio is also less in top gear...? how gear ratio will be executes??

[viv.nomad]

top gear is less bcoz it is making much greater revolutions .. hence higher speed at wheels wrt per rev of the transmission’s output [is it cam??].

very high ratio of low gears means engine is transmitting very high torque \ power when it is needed the most!!

R15's sprokets are, front 14 and rear 42.

Hey Joel, wat about the RTR? The newer O-ring ones?

All the RTRs have the same sproket sizes and ditto sprokets. Only the chain has chnaged on the RTR FI and refresh.
Its 13/44.

I think you can take the data from my image posts. It's a Rolon Manual, giving all front & rear sprocket details :-->

http://www.xbhp.com/talkies/desi-bikes/6145-world-sprockets.html

See post #14 for the data you need...

But, I'm confused. Maybe merging the thread is better than reposting the data, What do you say?

[Shreeni0403]

RTR FI AND RTR Refresh are same or different..!!!

@Samarth 619


added direct link to ur post!

all i wanted was precise info at one place! to merge or not to , is up to mods!

[Samarth 619]

^ What is the confusion dude??

I clearly mentioned post no. 14 in ALREADY GIVEN Link.. So, have a look and you can add all the data.

Any merging, if supported by Mods, is acceptable by me ...

sprocketing for p220 dtsi

hello friends...
i am thinking about sprocketing on my p220 dtsi....i want a very good acceleration but want only a slight decrease in top speed

how many teeth should i go for rear sprocket?
should i leave the front sprocket intact?

what other things should i keep in mind while getting this done?

[Aryan]

Query Approved.

[jd666]

^^ you will need to increase the number of teeth at the back.. Increase by 2 should be enough to give you what you need... the issue will be which sprocket are you looking at?? the P200??
