    This thing is defiantly 5 star. What a brute of a gear. Can't believe all the little spacers, circlips and tiny width of the factory gear. Mine had 7500 km on it amd was showing its age. Directions are perfect and easy to follow.

    What a nice gear, came with great instruction from td. I went with a 22t for my srx and it made my chain alot more straight and not so much adj needed on the adjuster. Gear is so smooth on the shaft. My stock gear had 7000km on it and wasn't too bad but this was on a stock tune and this year I will be adding hp so it was a no brainer for me to toughen up this yamacat.
