Hi Guys

Quick question. Which of these front sprockets is correct.
The old one is more offset outwards with the sprocket face to the outside.
The new one has the sprocket more central with a boss either side.
The reason I ask is that the old sprocket has signs of wear on the outer face implying that the chain is "wanting" to run more centrally so I'm wondering if it was the wrong one.
Someone must know.

The old sprocket looks like it may be a 900ie Monster item. Last two on my 907 looked as your new one does.

black907,

Here are pictures of the correct sprocket. Notice it has the same size "boss" on both sides. The retaining clip that is held on with the two screws into the sprocket fits in a groove on the spline shaft. This will set the sprocket on the shaft in the proper location.









I say go with the "new" one on the left.

Thanks for that. I went with the new one in the end so its all good.

Check the alignment to the rear sprocket to give you the best answer.
- Square the rear axle to the swing arm pivot
- Use a laser or string to show the where the front sprocket should be.
- Pick the one that fits best.
(easiest if the chain is not installed)
