Nice sprocket

My only beef is that it would be nice if it cake with new bolts. Will not work with original bolts. Oem sprocket holes are flat. The holes on this one are beveled.

JT steel rear sprocket

It is a bit heavier than an equal-size aluminum sprocket, but my experience is the JT steel sprockets last longer. Fit was perfect, and the price is right.

Needs spacer on FZ1

Nice sprocket, good for going from 190/50 to 180/55 tire on Fz1. Didn't line up right - needs a spacer or something so it doesn't damage the chain.

JT 520 steel rear sprocket. Suzuki rm125

Great sprocket. It fits perfectly and holds up well. I've been running my bike hard and it's showing no wear so far running 28hrs on the sprocket. I'd purchase again definitely if it ever does wear out.

52T rear sprocket on 2007 Ninja 250

Came nicely packaged, and was a direct fit with zero issues on install. I paired this with the 15T front sprocket and am very pleased with my new cruising RPM's. Now the bike feels "ok" at highway speeds vs the previous high RPM struggle. Almost a 1,000 RPM drop in 6th. 6th gear going up a hill may require a down shift now to keep speed, but the pros far outweigh the cons for this change.
