Hi to all.
I have a 1975 XS500 (I think). It has 2 piece head, oval exhaust ports and cast wheels with rear drum brake which doesn't seem to fit into 1975 as parts suppliers seem to think spokes should be fitted.
I owned a new XS500 (one of the last models) in 1978 which I thought was great back then but circumstances forced me to sell it after a couple of years.
I bought the one I have now about 20 years ago but it was not so good and eventually it was parked up and neglected. Now I'm trying to get it get it back on the road.
I have found much assistance from the forum and thought I really ought to join.
Rob..

Welcome!

A cast real wheel with a drum brake. That's unusual. They may be aftermarket wheels- post a pic!

Yes, please post a photo if possible. To my knowledge no 1975 Yamaha models came with cast wheels so I suspect they are Lester aftermarket and that resemble the wheels that Yamaha started using in 1976. Are they painted black or in natural aluminum? From 1980 the SR500 rear wheel incorporated a drum brake but it also has a much different sprocket hub and cushion drive from the 500.

The cast wheels are both marked "Yamaha". Front says M18x1.5 rear MT2.15x18. I think they are from an XS250, indeed I have purchased brake shoes for a XS250 and they seem to fit. Any recommendation for tyres to suit?
Thanks.

Your wheel rim widths are the same as those on the 1976 and up XS500 but the front wheel diameter is one inch smaller. So you will need as tall as front tire and as short a rear as possible to keep the overall ride heights close to level. I'm a big fan of the Avon AM26 tires on my bike and fit a 3.25-19 front and 110/90-18 rear. Those are both 26.1 inches in diameter. For your wheels I would recommend using a 90/90-18 front and a 110/80-18 rear. Those are 24.4 inches front and 25.3 rear so the radius difference will be just about 0.45 inch low at the front. That shouldn't be a problem but the bike will steer a bit quicker than stock. By the way, those are a nice lighter pair of wheels and will be rewarded with some better handling.
