Countershaft sprocket

I've had good luck with Sunstar sprockets before that's why I bought this one. I've only rode it a couple of times but seems to be working ok.

Just the ticket

Replaced my sprockets and chain after the chain wore out. My original front sprocket had a rubber cushion and I wondered if this one would be loud since it does not have a cushion. No problem. I can't hear any whine or clacking and it cost a lot less than the rubber equipped sprocket.

Trailworthy DRZ 400S

Combined with a 47 tooth rear sprocket the 14 tooth front sprocket will certainly give your DRZ trail manners. But be forewarned that you will lose about 10 MPH top speed on the road. So unless you like winding your engine tight, be prepared to trailer it to the trail head! The fit of the sunstar sprocket was good, be sure to recheck the torque of the 30mm bolt after the first ride, and occasionally afterwards just to be safe.

sprocket

Good service & delivery. Thought I'd try one tooth higher than stock 16 on my gs500f. Lowered rpm about 500 at the same previous speed and shifting intervals seem smoother. I'd recommend it depending on your riding style.

SPROCKET

I like the sprocket but definitely not the quality or as lightweight as other sprockets I’ve owned, but seems to be durable.

great product bad fitment chart

I like the product company they’re great, but going by the fitment chart from the site the sprocket didn’t fit.
