18 tooth sprocket

Really...Really? Punch it Chewy!!

What year and model bike is that?

I have 10 to 16 tooth sprockets for the 82-88 stuff. For a dirt bike to be able to use an 18 tooth sprocket the transmission output shaft must be pretty far from the swingarm pivot. Of course the way around this is the cts BMW/Husky in the 450cc range.

My guess is this is a short travel suspension kind of like street bikes that seem to have significantly larger sprockets on the front than dual purpose dual sport and off road bikes.

A larger sprocket is more efficient, at least that is what I read somewhere.

That’s right out of the owners manual for my 71 Enduro 360C. Has a 4 speed trans. My uncle purchased it back in 73 or 74 so it’s possible that it was modified prior but it had a 13 tooth when I got it.

^^^^^^ That's Really Puuuuuuurdy

those early engines had a bit of room so an 18 for desert racing would have been a possibility. especially with a 4sp

Looks just like the rolling chassis on my 69 360 Sportsman I had in 1974

Should have parts back from chrome soon along with the tank next week. Can’t wait!

Looking very nice. Since the Sportsman was an enduro/street model it stands to reason it would come with tall gearing.

What are your plans for it, a rider or display?

I do plan on riding it somewhat, would be a shame to let it collect dust. Bike had just under 1800 original miles so most internals were in fairly good shape. Has a new rod kit and piston but still on stock bore, just cleaned up. I guess I could start a thread under restorations for before and after pics.

Before and after pictures would be great.
