Friend of mine has a 08 sdr. We have been looking all over for a set of short stacks for the bike but can't find anything because the sdr throttle bodies are 4 mm bigger than the regular sd throttle bodies. Anyone have any insight on this topic? What short stacks might work or who makes a after market velocity stack for the R? Thank you in advance.

RC8 stacks are short and fit

So the rc8 uses the bigger 52mm throttle body?

Order em and find out They're only $20.

Here are some threads on intake mods:
