hey guys Im doing a little research on a dirtbike my grandfather had 20 years ago. He cant remember the name of it but according to him it was a four speed with a rotary shift pattern. Pretty much if you in fourth and you shift again it goes to fourth and so on. I would like to get him one as a gift does anyone know what the model and company is??

 

I had a Bridgestone 100 that had that kinda shift pattern..when you got to 4th... if you shifted again you got neutral and then 1st again.

 

Some Bridgestone motorcycles had the ability to changefrom standard to rotary shifting. They stopped manufacturing them in 1970.
