Cannonball SSK-S Transmission Base Plates

Bullet-proof version of the stock 1965-1985 transmission mounting plate which is guaranteed not to bend or flex. Precisely cut from high quality S 355 construction steel, with 2 square front holes to work with carriage bolts (stock equipment 1977→). Unlike original plates it is machined out of one solid piece of steel to provide extra rigidness. The two-window design makes it compatible with pre-1965 transmssions, too. However, you will require a custom primary chain tensioner in these applications. Recommended when using a Cannonball SSK-S electric start system or a high performance engine.

The Cannonball StealthStarter system converts 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.

The Cannonball SSK electric start system bolts between kicker cover and transmission case. The stock kick starter can be retained. Due to the system’s low profile, only 19 mm wide construction 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 extended throwout bearing, battery, wires and starter button/switch.
If the bike is still equipped with an early stock 6 V electrical system, you will have to convert this to 12 V. Depending on the configuration some other options are available separately.

Since the kicker cover moves 19 mm to the right the following modifications may be necessary:
  • A stock 2-1 exhaust system will have to be routed slightly outward to compensate for the offset of the kicker cover.
  • A longer clutch release lever will be necessary on rod actuated configurations like Moustraps or Footclutch. A longer lever can be ordered seperately if needed.
  • A extentended throwout bearing M U S T be ordered seperately for your type of clutch pushrod since the stock pushrod will be 19 mm too short.

In case your bike uses the older 47698-65 transmission mounting plate with the extension for the primary adjuster screw, the extension needs to be removed or our Cannonball SSK-S transmission mounting plate needs to be used.
