You got to love the pre unit Triumphs
Treat your pre unit to the best belt drive available from one of the best motorcycle parts supplier in the business LOWBROS CUSTOMS

Ultimate belt drive
You won't be disappointed if you purchase one of these belt drive. I have purchased several of these and have no regrets.

Awesome belt drive
My 2nd purchase of this belt drive because simply they work so well.

Bob Newby belt drive on triumph pre-unit
Looks so good I almost considered an open primary even though I like the stock look. My bike took careful setup to make it work in stock covers without rubbing. Had to add 1/4 inch spacers between inner and outer cover and move inner cover inboard by removing 1/16 inch from spacer between primary and engine plates. Great upgrade from wobbly worn out setup.

I have not installed it yet but you could not wipe the grin off my face when I opened the box !!! I have never read a bad review for this clutch and the " bike candy " look justified the cost for me . Oh yeah and thanks Lowbrow for all the cool bike stuff you carry !
