Cannonball Electric Starter Systems

Converting your classic kickstart-only motorcycle to electric start. After installation you just push the button or turn the key to fire up your classic Big Twin.

In the SSK series (K for kickstart drive) the starter motor engages with the bike's original kick start system. Available for models with Rigid frame (SSK-R, R for rigid) and swingarm frames (SSK-S, S for swingarm)

In the SSC series (C for clutch drive) the starter motor engages with the clutch hub via a starter sprocket. Available for Big Twin models 1937-54 (SSC-E, E for Early) and 1955-57 (SSC-L, L for Late).

You will find a detailed starter system comparison chart linked directly to the individual articles.

The Cannonball SSK electric start system bolts between kicker cover and transmission case. The stock kick starter can be retained. This intermediate housing, measuring just 19 mm, will be the only thing visible. Due to the system’s low width the overall appearance of your motorcycle will remain virtually unchanged. Primary drive, primary housing and oil tank will stay untouched.

Installation is fairly easy and straightforward. The kit includes everything needed for the conversion except for the battery, wires and starter button/switch which must be purchased separately. Depending on the configuration some other options are available separately.

Since the kicker cover and with it the clutch release lever move 19 mm to the right the following modifications may be necessary:

A longer clutch release lever may be necessary on some configurations. A longer lever is available separately.
A longer clutch pushrod will be necessary. Depending on the pushrod/throwout bearing used on your bike a special extended throwout bearing is available separately to fit your pushrod.

The stock 2-1 exhaust system will have to be routed slightly outward to compensate for the 19 mm offset of the kicker cover.

If the bike is still equipped with an early stock 6 V electrical system, you will have to convert this to 12 V.
A longer clutch pushrod (part of delivery) will be necessary. Depending on the pushrod/throwout bearing used on your bike a special extended throwout bearing is available separately to fit your pushrod.

Original rear fenders need to be dented. Alternatively, the included sheet metal “dent” can be welded to the fender.
