About 6kg I think mate, but not only that, it's where you reduce the weight that counts, all high on stock and low on the arrow so reduces it significantly.... I've only ever rode em with these so always scratch my head at your 'heavy' comments tbh... Felt fine to me tbh.
MV have brought out an RR version of the Brutale 800 140 HP / 168 Kg That's a pretty awesome power to weight ratio BRUTALE 800 RR Motorcycle | MV Agusta
I know this is an older thread now but have to comment! Had A street R before the blade and was a cracking bike. Great fun and torque is very surprising. Chassis is absolutely bang on. Phenomenal brakes. Never enjoyed cornering so much! Speed is a very good bike but not as fun in my book. I don't think there is a more fun to ride on the market at the moment.
only one good answer.... build your own streetfighter from a blade.... or gsxr... or zx10 = real power & comfort this is mine
