Stock......err no.
Tyres are Pirelli Diablos.
Silmoto carbon fibre exhausts, it has a TFI techlusion fuel injection gizmo, Braking Wave fully floating front discs with Brembo 4 pad monobloc calipers, rear Braking Wave disc & a lightened flywheel.
It's ok in heavy traffic but it's great as soon as you get out of town.
Certainly no stumbling to be found...as Paul says, smooth power all the way to the limiter...
