JT sprockets question..

I see the 17, and even 16 tooth front sprockets on ebay for like $16 or so... anyone ever used this brand? Good, bad...or just ugly? I bet the 16 would be a slap in the face sort of 'wake up' on the ZX11... hello 3rd gear wheelies.... lol

Any experience with these appreciated... basically just thinking out loud..

Johnny

I am pretty sure mines a JT up front and a spupersprox in the rear.
Supersprox are awesome rear sprockets, aluminum inner with harden steel teeth outer.

Blaine, I believe these were steel... yea, I went and checked...they are steel. I tried one of the alum sprockets years back and that is about what it lasted me...maybe a year or so... I even see where some now are alum in the center with a steel outer ring... seems like asking for problems with small reward possibilities... I would only buy steel now

.... copy/paste from ebay page... "JT Front sprockets are manufactured from SCM420 chromoly steel alloy"


http://www.ebay.com/itm/JT-Front-Spr...lXlunZ&vxp=mtr


here is the 16 tooth... I looked at it and the 17, both steel...but they say in the text they do offer lightweight alloy sprockets for some applications... this 16 looks pretty light the way it is drilled and manufactured...

What's the benefit of an aluminum front sprocket??, obviously it will be weaker than one of steel. I'll never put a thing like that.

While they exists for DP and moto crossers, I never saw a front sprocket made out of aluminum for big bikes like ours.
The only benefit is the weight loss (and the absence of rust if you insist...). But for bikes likes ours that are in the 550 lbs range, nobody would notice a few ounces loss like this. And the life span would be dramatically lower.
Even for the rear sprocket, I only use steel units as I always try to get the longest possible life out of my parts. Consider also that the chain usually needs to be replaced along with the sprockets and it is the chain that is the most expensive. So, a shorter lived sprocket will also involve more chain replacement. And steel rear sprocket costs less than an aluminum one.

The "hybrid" ones (steel teeth on aluminum carrier) is a great idea as it combine best of both worlds. But they do come at a cost.

The weight of my 11 and the way I ride it make lighter sprockets a non logical choice. But that's just MHO...

I ride an overly large and needlessly powerful motorcycle. Just starting it makes a polar bear die.
