None, but how cool is that. That's a proper 50. Straight out of the 1960's. Based on the K50. Four speed box. No engine braking, small drum brakes and cross ply tyres - makes for excitement on every ride.
These were made for far east markets - India, Indonesia, Malaysia, Philippines etc. Great looker. Pretty sure they weren't an official UK model.
Put decent tyres on it. Spoked wheels will likely mean tubed tyres, which might limit your options.
For short hops it will be good fun.
Buuuut - it's an old school two stroke. Buy decent quality two stroke oil, not cheap crap, or you will regret it.
AND - warm it up, warm it up, warm it up. Kick it over, jump on and ride away - is a recipe for the premature death of an engine. Especially such a small stroker, that has to work so hard.
Speed: fastest bikes in the world old Suzukis, by the time you hit 25mph it'll be reading 40 on the speedo
. Get the carb up-jetted and the head ported and it will do 40! ( Do that the first time it seizes... because it will!). I'd run it on super unleaded. At 87km per litre it won't be expensive!
Do yourself a favour Ibbz: Book yourself an hour or two with an instructor, even though you don't, technically, need to. Especially if you are thinking of putting your boy on the back.
That's a classy little bike! Good man
