So figured i would drop this here since i have not seen anything posted about this any where have you guys heard anything bad about these i have a R45T on order along with their F13T and a new RK XSO chain i may try both together or just either or they both seem to make enough improvement alone or together to justify the experiment i do not care so much about top speed don't live near a major highway and really only commute back and forth to work or ride the back roads

There can be a noticeable difference changing to an aluminum sprocket and a chain more directed at performance. In terms of changing the amount of teeth on the sprocket, there are countless threads already

Great, do post your review. I have the r6 throttle done also. I have the 13T on order, should be here next week. Just contemplating whether I should get the 44T or 45T rear.

Well i put the 13T front sprocket on worked so well i managed to get pulled over lol. The bike feels great with the front sprocket pulls harder in all gears. I know my speedometer is off by a nice margin but the bike gets to 100 in no time compared to the stock 14t. I wanted to see if the front tire would come up the way i ride it and it didn't so i was happy about that. Now if i had to describe what the sprocket change feels like while on the bike. I would say it skips all the useless lower half of the power band with the stock sprocket keeping the bike in the fun part of the power band easily. Tomorrow i may put the aluminum 45t rear sprocket on with the new chain i will post as soon as i do though
