06-09 R6s but not the 06-09 R6. Not even sure if the 06-07 and 08-09 R6 tranny can be swapped out.

 

06-07 R6R crankcase part# 2C0-15100-00-00
08-09 R6R crankcase part# 2C0-15100-01-00

02 R6S crankcase part# 5MT-15100-01-00
09 R6S crankcase part# 5SL-15100-02-00

if you wanted to swap out the transmission you need to swap the complete motor unless someone you know can swap the internals but you might as well just get a used R6 motor from a newer 06-09

 

Nope! That info may be correct but you don't need to swap the motor. Go take a look at the transmission parts. I just looked through all of them comparing '03R6-'09R6s and everything is the same part number. So the case may have a different part # for some reason but the transmission which he was asking about is identical.

Like I said, 03-05R6 06-09R6s are identical trannies and can be used in the 1st gen. To adress your vice versa comment I'm sure you could use a 1stgen gear box in a 2nd gen or R6s but why would you want a crappy gearbox more prone to problems. That's if I understood what you were trying to say correctly.

 

I just find it so odd that the 03-05 will work with either generation but not vice versa
