Yamaha Riva Razz 50cc SH tire clearance, especially rear

Post by chevy59tom »

My father got this Riva Razz at a yard sale and it needs new tires after 10 years or more. The specs call for a 2.50-10, but I wondered if anyone knew if a 3.00-10 would work on rear for extra support and performance. Will it clear the rear wheel housing and fit on the rim okay ?
I'm sort of new at this.

I went to my Yamaha dealer and purchased two new tires for my Razz for about 45 bucks each. I went with a slightly larger tire but not a 3.00x10 though that size should work. Check with the dealer. They're very competitive and really good guys.
Good luck. These little scoots are a blast. I'm a cruiser rider and have fun with the mini as well. :lol:

To answer the OP, a 3.0 tire is pushing it....there's a real chance you won't have enough clearance on the back of the engine or at the fender or at the shock. You can usually go up one size (ie. 2.50 to 2.75) but going all the way to a 3.0 is risky and at best it'll throw your gearing pretty far off (ie. 15-20%).

And not to mention that it'd throw off the speedometer too. It'd have to be recalibrated to be as close to accurate as possible.

Just picked up the scooter after the dealer put original size 2.5X10 on. Couldn't fit the larger size as you indicated would be a problem. So, I'm very happy with the dealer and would go back no problem. I think that's the most important part of the experience. They're a great group and we laughed when we talked about the scooter. :lol: Very knowledgeable guys.

Only changing the size of the front tire would do this. Changing the size of the rear tire will affect your gearing, but not the speedometer.

very curious to know what the dealer charges to change front on rear tires. I'm tearing down my helix right now and figure this is the best time to do the tires since all the body panels, etc are off. Yes I know helix is much larger.

I'm just looking for a ballpark.

$35 to 50 per tire which seems a bit on the high side I know but since I hurt my back badly enough for surgery, I'm not doing any wrenching at all for a while and I needed mine done pronto.

I got great service and they did them while I waited so that was a bonus. To me it was worth it.

I have a 1988 Yamaha razz my mom has got it for me it's my first vehicle I have ever owned. I bought it a new battery but unfortunately someone has flattened my back tire on it I was wondering about how much would it cost me for new tires for this and where could I get it.

I’ve ran 3.0x10 on my 1988 razz for 20,000 miles no problem. It’s a real close clearance, but as long as your tires are aired up you’re golden
