DESCRIPTION

A complete, top spec and lightweight primary drive kit for your Norton twin, utilising the Commando diaphragm clutch

Comprising 32T front pulley, 30mm wide quality 8mm pitch HTD drive belt, and our standard 68T lightweight drum. All wearing aluminium parts hard anodised as standard.

Front pulley is only available in 32T x 30 wide as standard. From time to time, we do make other sizes & widths, but you need to check first by email. We tend to have 30T & 36T available. (30T will increase the centre distance by about 3.5mm, 36T will reduce the centre distance by about 7mm).

Belt lengths offered are:

880mm = 235mm centres (Commando)

920mm = 255mm centres 

960mm = 276mm centres (Most Dominators/650SS/Atlas)

976mm = 284mm centres

1000mm = 296mm centres

As standard the kit includes our standard 68T clutch drum & sealed bearing ONLY. You need the centre, plates, diaphragm spring & big circlip from a standard Commando clutch. We do not sell these standard parts. We can sometimes also supply a 70T clutch drum, but you need to first check by email (this will reduce the centre distance by approx 4mm).

We offer the option of a lightened drum, 6 large holes in the back, recommended as it lets plate dust out which tends to accumulate at the back of the clutch and impair the release. Some people consider lightening unwise as it obviously reduces the strength of the basket, but unless you have over 90  bhp we don't consider this a problem.
