Questions & Answers
The answer is yes.
With the 530 chain I had on my bike, getting the drive sprocket off was easy. The jammer should fit the width of 520 chain, but the pitch is probably correct. Motion Pro can probably proffer the best answer. I'm out of town, and I can't measure the width to make sure.

It does not sit flush between the chain and the sprocket on the first try. Anyway, let me just give it a try. As a result, the item got a little gouch, which involved taking off the paint and filing the iron It doesn't matter what holds the wheel in place, just the fact that it holds. Therefore, I begin to apply pressure on it and it simply keeps giving in therefore, I would just buy a sprocket holder tool instead. While it's a good concept, even when I tightened my chain to the maximum tightness, I was not able to take off my front sprocket.

My jaw dropped when I saw how small they were. The chain and countershaft sprocket are the same size, so for my 428 530 chain I expected them to fit between those. I find it to be quite small. It might be possible to use between the rear sprocket and chain, but I'm not sure. I really like the way this is made.

I do know it works, but I'm concerned about all that pressure stretching or damaging the chain if I tighten the front sprocket nut to 100nm. It was much easier to apply my rear brake just to start with.

A KTM 1190 Adventure is my bike. On this bike, the chain is a size 525, which doesn't fit between the sprocket and chain. It does work, but something like a rag or old dowel would be just as effective.


In trying to jump over it, the chain became tangled with the tool that was not able to fit between the chain and sprocket. This is a very common GSX1300R Hayabusa sprocket and chain that was properly adjusted using the motion pro slack setter chain tension tool, which is a wonderful tool, but the sprocket jammer is not so great.


I did notice that it got very pushed back by the driven sprocket tooth, however it held up well. Maybe it should be made out of a stronger.
