Colombo & Bariani have been manufacturing both original equipment and performance camshafts for cars and motorcycles over 60 years. This 10.9mm lift camshaft is excellent for fast road 1300/1600 engines, providing a smooth stable idle, good torque at low rpm, low exhaust emissions and substantial power increase. Duration is 280 degrees. As with most high lift camshafts it may be necessary to modify the valve guides and the lip of the follower bore holes especially if being fitted to a cylinder head from a 1300/1600/1750. This is one camshaft only, they are usually sold as a pair.
