hey I'm new here and I was wondering if anyone had some info on where I might find the gear ratios in the transmission. I'm a student doing a senior design project and I need the gear ratios in order to design a linited slip differential for our formula racer. The engine we have in the racer is from a cbr 600 but I'm not sure what exact bike. sorry I don't know too much about the differences in these bikes. If it helps PC35E-2229339 is engraved on the transmission. Thanks for the help in advance.

 

Would have to know what CBR it came out of. For some rason that number doesn't come up as a good number in any parts list. Pull the side cover off and it should have a part umber on it, then type that into RONAYERS "were used" seach and it should tell you what year and model.

 

thanks. I can't do that right now though the engine is at school. I'll definitely do that soon though.

 

Just found out today the bike was a 2001 CBR 600 F4i. vin number is JH2PC35021M209628

 

were you talking about the side cover of the bike?because all we have is the engine and a few other parts. It came off of a wrecked bike.

 

Here you go, internal transmission ratios for the F4i.

1st Gear Ratio 2.930
2nd Gear Ratio 2.102
3rd Gear Ratio 1.592
4th Gear Ratio 1.377
5th Gear Ratio 1.190
6th Gear Ratio 1.075

 

Thanks a bunch. you have no idea how much this will help me!

 

Hello Jason,

I am working on a crosskart project and are really interested to know where you got these numbers from. Thanks a lot!!
