That whole back end does look very familiar to a M3W owner. ABS and/or traction control looking at the rear wheel sensor? A wider axle with a Continental made drive belt rather than the Gates. The bevel box looks externally the same although must have some better internals than the Quaife noise box, interchangeable maybe? An alloy single side swing arm would have been so much better although more costly I expect. Nice close fitting mudguard as standard?
