HELP SPUD! What Sprocket Pattern is this? (Pic)

[Mike_51_deluxe]

I really need to get a smaller rear sprocket on this thing, but its has a unique bolt pattern. Anyone know what fits this hub? Its a 6 bolt patter, but grouped in two's as you can see in the pic

looks like a Suzuki, try a 93 Suzuki dr200, good luck

Think this would work?

NO, that sprocket above is for 520 chain. you need 428!

Ahhhh, okay, good to know lol. That would have sucked!

I asked this in another thread before seeing this one, but can you measure the sprocket, Mike? Tell us the bolt diameter, the bolt circle and the center diameter.

X2. To be a little more explicit, we need to know the diameter of the circle which passes through the center of the bolt holes, the diameter of the bolt holes, and the diameter of the circle in the center of the sprocket.

Thing is non of the holes are across from each other so I cant really get a good meassurement of that :(

I'm sure this Chinese sprocket is a copy of a Japanese sprocket, Mike. I encourage you to search the catalog at the J.T. Sprockets website.

Mike, if you're looking to figure out the bolt circle, remove the sprocket and trace the center hole and the bolt holes on a piece of paper. Using a ruler, measure from the center of a bolt hole to the edge of the center hole. Add that distance (in mm) to the center hole radius and write it down.

Using a compass from a mathematical set, set the compass to length you arrived at. Place the point of the compass in the center of a bolt hole and make a small arc with the pencil end in the middle of the center hole. Repeat that with another bolt hole. Where the two arcs intersect is the center.

Measure from the newly-discovered center to the center of a bolt hole and multiply the length by two. That's the bolt circle.

There's a more correct way of achieving the answer (and probably a simpler way as well), but this will be really close. Make sense?

[Weldangrind]

If you don't have a compass, just take the length from the center of a bolt hole to the edge of the center hole, add the center hole radius and multiply that answer by two. There might be a larger margin of error, but you'll still be close.

JT Sprockets skips right over the '93; they have a listing for '83 to '91 or '96 to 2011. In either case, JT says that the DR200 uses a 520 sprocket. http://www.jtsprockets.com/52.0.html?&L=0

Yes, I read your post.

[chrisdigital20]

sorry, the 93 was only imported to china, Europe, check out some European sights, also, is that a 428 chain fir sure, ? my shineray is but your is not a xr200 clone. i will do some research for you through my European connections,what year, make , model is your bike?

Yes, I read you post also, Chris. As with Weldangrind, I could not find the '93 sprocket available for sale in the United States, nor could I find a diagram for it.
