Title: "true" speed on M696 with 15T or 14T front sprocket Post by: fLUNX on June 24, 2008, 07:12:29 AM Hi for everyone,
I guess that it isn t very important, but has there are people who change the front sprocket of the M696. 15T for stock sprocket 14T for quicker bike I hope that I have done the right calculation. the software used is from: http://www.racingsm.org/vel.php (any tech doubt please contact site admin) I have done for 9000rpm (I guess that its the full throtle on the M696) and I have done another charts for 6500rpm (I think that it is a reliable rpm for engine and biker drive on "crusing" mode on) (http://img387.imageshack.us/img387/2817/m69615x459000dn2.gif) (http://img381.imageshack.us/img381/7562/m69614x459000wn2.gif) (http://img396.imageshack.us/img396/4999/m69615x456500qf6.gif) (http://img169.imageshack.us/img169/6714/m69614x456500ba2.gif) Regards, fLAVIO [thumbsup] Title: Re: "true" speed on M696 with 15T or 14T front sprocket Post by: nkryptit on June 24, 2008, 10:59:59 AM I was JUST wondering about these numbers in the shower today. Thanks for the preemptive strike!

I bet the top end is the same ith the 14 in real world applications. in a slop.... why not. I did it at 9000 because they claim it is the rpm where the max output power is. and of course the charts are in theory... only by math speed calculation. But I think that is a good clue about how short will be the bike versus stock sprocket. and remember that the speed indicate is the "real"... and not the shown at the "tachometer" at the bike...

Rear brake disc ?

An easier way to calculate is that the 14T will make the bike 6.67% "shorter" at any gear, compared to the 15T. (1/15 = 6,67) Title: Re: "true" speed on M696 with 15T or 14T front sprocket Post by: Armor on June 26, 2008, 08:54:08 AM Unless you can hit the rev limiter in 6th, you are limited by horsepower.
