Cannonball StealthStarter SSK-R Kick Drive Rigid Frame

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.

  • A longer brake crossover shaft will be necessary on all bikes using the original mechanical rear brake in conjunction with the original 2-1 or similar exhaust. A longer crossover shaft can be ordered separately if needed.
  • Original rear fenders need to be slightly dented for starter motor clearance. Alternatively, an aluminum “Dent” can be ordered separately. In this case the fender needs to be cut out to allow the “dent” to be mounted with the original lower fender mount bolt and the two oil tank/battery tray bolts.

Just like on a kickstart system the Cannonball SSK System starts the engine by turning the transmission mainshaft. And just like on a kickstart system you SHOULD NEVER actuate the starter with the bike in gear. If you do so the starter motor will move the bike forward no matter if the clutch is pulled. This can be avoided however by wiring the starter button through the neutral switch.

CB SSK on Custom Rigids with 65-up Transmissions

Installation of this starter kit on rigid-frame-bikes that use an 65-up transmission made for aluminium primary requires that mounting tabs on the transmission housing are ground down a few millimeters for starter motor clearance.

CB SSK Prevents Rolling Backwards

With the bike in gear and clutch disengaged, it does not roll backwards anymore. This is a helpful feature, when taking off uphill, particularly in combination with a foot clutch.

CB SSK with Reverse Gear Transmissions

The SSK Kickstarter kits will work with reverse gear transmissions.

  • with the bike in 1st gear and clutch disengaged the bike can be pushed forward, but does not roll backwards
  • with the bike in reverse gear and clutch disengaged the bike can roll backwards but cannot be pushed forward
