JT Sprockets JTF402.16 16T Steel Front Sprocket , black , 16 Tooth

Mounting was really easy, the part comes well wrapped and it works really good so far. Will keep an eye on durability though.

I've gone through 5 of these on my 2006 F650GS Dakar. I've yet to experience a problem with any of them, even when I've secured them improperly and the retaining nut fell off. They have always seemed fully functional when the chain wears out (and are replaced as preventative maintenance). I've been on two major support forums for over a dozen years, these are the most highly recommended sprockets there and I've never heard one complaint about a failure like the other reviews here mention. looks like corporate troll activity or something

It is a very particular item and I got it exactly as I asked.Quality of the product, price, delivery in time (and I am in Brazil!)everything OK.Travelling with my BMW Xchallenge much better now.

Just even better than the original one. I use it on my BMW G650 GS 2014

They fit loose on shaft and cause damage to splines. Very expressive repair when it t happens.

Price was Great. A little but of a job getting nut off but air wrench helped quite a bit. Install sprocket with stamped info facing out.

Received my order in two days, as advertised. First class purchase.

I purchased two front sprockets from JT (14T and 16T) and cannot use either... the splined bore has been chamfered on the back face where it's supposed to be a sharp square edge to locate against the step on the counter shaft and provide the proper alignment with the rear sprocket. When the OEM sprocket is slid onto the counter shaft it sits slightly proud of the end face of the counter shaft but when I slide either of these on, they both sit approximately 1/16" to 3/32" below the end face of the counter shaft preventing the proper preload of the belleville washer when the bolt is torqued. The splines are also incredibly sloppy compared to the OEM sprocket. I will not run either of these on the bike.
