 As the title states, I have a few things to pass on to those who own a MC-250B scoot. These things are answers to the reoccurring questions that I see all the time this forum. For the first question, does a larger tire fit onto a 250B scoot. The answer is yes but it’s very tight. I recently had a 130/60-13 tire that only lasted about 3000 miles. This was a Avon viper striker tire which didn’t last nearly 1 ½ seasons, so I decided to get another one. After looking for a few weeks, I decided on a really nice Dunlop tire. The only problem was that the size was a 130/70-13. Taken a chance, I purchased it and place it on the rim. When I went to install it, I found out that it wouldn’t fit on without some disassembly of the bike. What I mean by this that the seat bucket and right shock had to be removed. Once this was done, the tire had to be void of air as well. After fitting it on, I filled up the tire with air and turned the wheel. Well when the wheel turned, I was hearing a rubbing noise however this was due to the extra rubber from molding the tire. Unfortunately I haven’t had a chance to ride it to see if it really interferes with rubbing against the engine with pressure against the tire. The next thing is for those who are looking for 250B parts especially rear rims, they have them and they do fit. I place an order for one since day one the original rim had a slight bob to it. After checking the VIN and found that it started with 5RY and used the scooter with the designation of being a 5RY on the web site, I decided to give it a try. Yep, it was the right rim. Ship to me within a week since I live is NY and it was coming from CA. For all those who have complained about rear end wobble, there are several things to look at. The first is to look at the nut on the axle. This tends to loosen up and allow the rim to become loose and move on the spined shaft. Replace the nut. Better yet get another nut and use a jam nut to lock it in place. If the shaft nut is tight, the next thing is to look at the engine swing bracket bolt. This nut and bolt that is in the lower section of the bracket that attaches to the engine has a tendency to loosen up as well. I’ve had this issue for some time and with the seat bucket out I had a better chance to see it wobble clearly. I broke out the wrenches and tighten it up and the wobble was no more. This is another area where you would want to place a second (jam) nut against the original one. This will lock it into place and prevent it from loosening. I hope that this has help some of you that has asked these questions and what to do.

A tire grows from centrifugal force. Faster it spins, the bigger it gets to a point. john

This I know. I'm hoping that the tire doesn't grow that much. I can tell you the the Dunlop tire that I used is that it's a very stiff tire. I'll see very soon due to the fact that I need to replace the swing arm.

I ran with the Avon Viper 130/60/13 and the tire didn't last. As I went to deflate it the tire folded in half. Didn't get nearly 3k out of them. I'm looking for longevity and I'm hoping that the tire that I have now will work. These are recommend for the larger 400 and 650 Scoots.

Yep, you want longevity then you have to go with harder tires that is what makes them last long. Softer tires for a smoother ride will not last as long.

Even with the Avon (soft) tires, my shocks are so stiff, I still got a bumpy ride. I don't thing that it will make a difference.

Well they are not caddillacs so get some softer shocks or ones you can adjust for softness or hardness.

Do your rear shocks have adjustable preload settings? They may be cranked up too high. My scoot (YY250T 244cc Honda clone) has adjustable rear shocks. I am running 26 pounds of air in the front and 32 in the rear with the original tires. The rear shocks are set to the softest setting. I have no complaints with the ride quality. The rear gives me a very comfortable ride while I get a little road feedback from the front. Check your tire pressure and shock settings (if any) - it can make a big difference.

JR - Will those tires fit on my MC54 with the 244cc? I'm not sure? Look and see how much clearance you have between the tire now and the crankcase. With the 13/60 on my 250B I had about 5/8" of clearnace, now I have about 14" with a brand new tire fully inflated to give you a idea of what you need. Of course the 120/70 will fit the front I know.

Unfortunately my shocks have only a spring with a fixed plate. I've been looking around but some of the shocks that I've seen are more expensive then car shocks. Go figure.
