The motorcycle has 35 000 kms (21700 miles) mileage, the sprockets and chain are new.
If the sprocket is OEM you have a little wear on the shaft-if it's after market like JT the tolerances are a little loose- which is normal for them-either way is it time to worry NO-the bike doesn't have the HP to ripe off splines -most OEM sprockets are SunStar because of the tight tolerances-I much prefer them and will not use JT products-as the video showed a little molly grease will help alot- not just for rust but to give the splines a cushion
