Magician Rear Sprocket

[Magician16]

I've searched, but I can't find a part number on here for a rear sprocket. I am looking at the standard 45 tooth or maybe a couple teeth less. My chain needs replacing, and I've got both a 16 and 17 for the front using an x-ring chain.

The Magician is based on a Yamaha Tricker 250 that was sold outside the USA so there are no USA sources I am aware of except maybe Yamaha. I cannot confirm absolutely but it appears parts are identical if looks are an indication but again that is not confirmed. It is one of the few motorcycles sold here that appears is also popular in China and that is a good source for parts but will take some special ordering and a long shipping time. Because it was sold in Europe the internet has parts sources for the Tricker.

Unless your sprocket is worn or damaged I would consider using what you have. The Magician rear sprocket is an odd duck and due to its design limited to 45 tooth unless you have it custom made and even then it will require fabrication to get around the cush type rubber bearings in the sprocket bolt holes and size is limited by the wide bolt pattern spacing.

I personally am just gonna stick with the standard 45 tooth style from JT Sprockets.

Good info. I had found a source in Italy. I'm not sure if the sprocket is worn, but the chain is bad. I have always replaced sprockets with chains on my Japanese bikes.

You can have one custom made for a reasonable price from pbi sprockets.



Center Hole Sizea: 45mm

Size of bolt holes diameter: 8mm
Measure the circle diameter through center
of all bolt holes: 136mm



that's the info you need to have it made, just tell them the number of teeth you want.

I put on a DID x-ring chain today and a 16 tooth sprocket. There's no way to get that chain in there with a 17 tooth sprocket. I had bought a 132 link chain and ended up cutting off 3 links. When I went to put the keeper on the link, it flew somewhere into a dark corner of the garage. Luckily I had a couple extra links laying around. The rear sprocket looked new as did the front 15 tooth that I took off.

This is what I had to do to get it to fit. Has worked with no issues since.

I put the 17t on with the keeper to the inside, but the sprocket I have wouldn't work. Maybe a JT would; this is a Chinese one that I have.

It may be because the x-ring chain is heavier than the o-ring. The rating on the x-ring is 350cc and like 7420 lbs. tensile strength.

With the 16t on, I did a shakedown run and it will go 60-61 with gps about 64-65 on the speedo. It runs out of power, so the 17t wouldn't do me any good anyway.
