Removing weight from your alternator rotor has two effects, 1) allows your engine to rev quicker giving faster acceleration and 2) reduces the engine braking effect.
On a standard Triumph twin, if you go down through the gearbox from high revs and use engine braking to help reduce speed, the rear wheel tends to lock with loss of control. Reduction of alternator rotor weight helps here by not giving such violent engine braking.
TTP found what they consider the perfect weight reduction for normal/fast road riding to give good acceleration without engine snatching at low revs and is available for all air cooled twins.
