but it was as light as an 07 rr a long time before there were any rr's

 

and it has a dual piston rear caliper......

 

Honda should bring that **** back to life with some extra hp

 

07 600rr???

 

Those 400cc sportbikes are horrible for stunting, just so you all know before you buy one...

 

Please, explain why did you think like that?

 

I think this spec. are CBR400rr 1989 model not 1998. The last model are 1992-93.
thanks for detail
