RSA/RSW and Derbi Power Curves

Derbi was before RSA came along, so no comparison.
Later Derbi badged bikes were Aprillia 100%,was just labelled Derbi for name sake.

What about Marc Marq winning races using a reed valve KTM against these rotary valves......... That's what you should be saying instead of kissing Lorenzo's arse every 5 secs. ;)

Ah Sam Lorenzo still won with 5hp less regardless of the intake ;)

Lozza,
No doubt it's hard to split those two riders.
If only we could throw them on good old carburetor 500's to weed out their faults. ;D
