Vortex 520 conv.

By Michael from Royal oak, MI

Pros: Went 1+ in the back with 1- in the front. Excellent acceleration. Easy install. After 3000 miles have seen significant wear on (aluminum) rear...worth it though, will still be viable for some time.

Cons: Wear, mentioned above.

Some slight decrease in gas mileage and increase in speedo error, but well worth it, and you will notice significant imporvement in torque in all gears. Does accentuate the throttle abruptness in low gears though. Worthy investment, and performs as expected. If you are more inclined to the track, go 2+ in the rear (a little much for commuting).

Great

By Justin from Gravette AR

Pros: This sprocket gave excellent torque and was shipped very fast. I can't wait to get out for more riding. With products like this one and the excellent customer service from knee draggers... this year should far surpass all the previous.
