This kit has been specially developed for BSA A/B series models up to 1965, excluding unit singles, but including the ex WD B40.

Comprising Eddie Dow style damper units in Dural and St./St. made on a CNC lathe then polished and assembled, multi-rate springs, fork bush and seal set, this kit provides everything needed to transform the front suspension.

All springs will compress with age, and as the newest A10 fork is 46 years old the standard suspension will not even be performing as the designer intended. The damper units give full 2-way damping which reduce dive, pitch and wallowing, particularly at speed. The multi-rate springs combine to tighten up the handling and roadholding, as well as giving a more comfortable ride. New bushes and seals ensure that everything is working properly.

The complete kit is £110.00

Multi-rate fork springs and the damper rods are available separately both priced at Ł41.00 and £42.00 respectively.

Sprgs. 11" length, 1.84" (46MM) OD & 1.41" (36MM) ID

Damper rods measure 482MM from the underside of the top nut to the bottom of the damper.

Carriage on springs £5.00, Damper rods £3.50, Springs and damper rods £6.50

A10 BIG END BOLTS (Large journal)

Parts ordered for my A10 rebuild includes a set of big end bolts & nuts. These I ordered from a regular trade supplier. I was appalled at the quality & was told that was all that was available. I phoned a few other dealers and couldn't find any better.

I then stumbled on an engineer in the marine engine industry who had had similar problems when rebuilding his A10, so had a batch made by an engineering company which supplies parts for F1 teams.

Made to the original spec to tight tolerences from the correct spec material, with rolled threads. This is very important as a cut thread can create what's called a 'stress raiser' which may lead to failure. I've put a set into my A10.

The nuts supplied are Clevelock self locking nuts provided by LP Williams

These are priced at £42.50 including nuts for a set of 4
