Loose additional unsprung, rotating weight with TPO Parts Titanium brake disc bolts! These are the bolts which secure your brake discs to the wheels and rear axle of the motorcycle. TPO's Titanium Brake Disc Bolts are machined from 6AL-4V Titanium with specially shaped FORGED HEADS, made specifically for MV Agusta brakes. These bolts are slightly stronger than the OEM steel bolts, but they are also about half the weight! Titanium doesn't rust or corrode like the cheap factory bolts do, so they will keep your bike looking great for years to come.
