Hello from France,

I've heard OS is going to release a new engine certainly called .12 TzR.

Main features :
- 2.1 cc
- 3 ports
- 16% nitro design
- long stroke ( like italian brands )
- 12mm crank shaft
- new case ( the case of the 18 TzR )
- new carb
- new agressive machined piston/sleeve
- Ifmar legal version and Efra legal version
- why not an OS Speed Division engine?? ( I dream....)

It will be presented at the Nuremberg Show on february.

Do you have more info??
