I have posted earlier the Yoshi Racing Engine Gear Set Teeth Count, but I forgot to post about the Yoshi Racing Engine Gear Set itself. So, here it is.
This gear set has a better gear ratio for the great power that comes with the modified 125Z engine. Usually, this gear set is used in drag racing with the front and rear sprocket modified to have higher ratio for better pickup. You can also use this one for track racing with the front sprocket set to 15T and rear 37T. This is a good ratio to be used with this gear set.
Also, SKF high speed bearing is a good addition to be used with this item for better power delivery at high RPM.

Item are available for sale here

Motorcycle-thai has released a spy shot for the Yamaha new bike for 2010.
I don’t know whether this one is for Lagenda or 135LC. It is because the headlight is like Yamaha Lagenda but the pilot light is like Yamaha 135LC. After further observation, I saw that the rear suspension is not monoshock but normal double shock.
What do you think, readers? Yamaha Lagenda or 135LC?
The answer will be out on 2010.
