Toothed Belt Drive

I spotted this on eBay and it looks a worthwhile modification to remove the problem of belt slipage.

On the Triumph setup, the toothed belt would replaced the twin v belts, but the v belt for the water pump and alternator would be retained.

The pictures show an interesting "outer" bearing.

Food for thought...
