Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Bevel Box - How long did yours last?

I've been reading the threads detailing the problems with the M3W: given the production volume the problems, especially with the bevel box, are a concern. But BMW has been fitting shaft drive bevel boxes to big bikes for years and they do have problems at times, possibly because the boxes are in the rear hub and are small, much smaller than the thing Morgan uses.

It does make me wonder why Morgan didn't use a shaft to rear hub, cost probably. But the short drive belt isn't elegant engineering.

So who will be the first to offer a triplex chain conversion? With a suitable oiling device a chain should last 20,000 mikes, cannot move from side to side and is unlikely to snap. It also can't make the noise a belt can make....
