By the time you have sold your Bullet and have another one your ankle would likely be quite ready to kick again.
I never got a chance to kick the Maico 400 again because the co-owner and others had trashed it by then. It wasn't the kicking back keeping me off it, but my ankle was to weak to ride it.
Kick back doesn't have to result in injury. Use the ball of your foot and anticipate kick back.
I couldn't afford a cycle with electric start and my next street legal cycle was a MZ ETZ 250.
There is no reason to be afraid of kick starting the Bullet. I'd take a KS only Bullet over an ES any day and I actually removed the ES from my 2003 ES.
Use the ball of your foot, pedal just slightly more forward than what feels right, and anticipate to slip off. Kick back will just be a mild surprise then. If you don't have the strength to kick like that, leave the vehicle to somone else. That's all there is to it.
Well, I'm just posting this so people reading this thread don't get paranoid about kicking their Bullet or any other vehicle (outboards too, don't lock on to the handle!) Just don't do the lazy a$$ way of locking your boot heel on the kick starter pedal and then use your weight - bad form. Myself and others have paid for it.
