Taotao has gotten into the 'race' scooter game with a new bike. Actually, they sold one that looked like the Dongfang up to last year. This new one is not as fugly looking as the Dongfang bike, except, look at the rear wheel! YIKES!!!???

thank you, yes it is I have some newer pics. I did a mock up of the belly pan extension. I'm gonna have to extend it for the underslung exhaust. It also helps me come to terms with the 15"s.
I figured I'll run 2 different setups. If I'm at a kart track that's smaller with tight turns. I'll put on the 14" wheels. If I'm go to a larger kart track. Where I can get the bike up to speed. Then I'll use the 15" wheels for more stability at higher speeds, even on full sized tracks.

LOL it's funny you say this. Back where I use to live. When I want to test my modded 165cc bike. To see how it ran at top speed. I'd get on the local road and go for it. Sometimes car in front would try to leave me. I'd be stuck to there bumper like glue. If I had a car behind me trying to keep up. I'd leave them in a dust, the road had some great turns. I always had on slicks so I plus I never had to touch the brakes....LOL
By the time I'd reach the end of the 2 mile stretch. I would sit at the light waiting for them.... The look on the faces was priceless. I had the bike geared for short track so it got to 65mph reeeeeaaaaallllll fast. And I always felt it need another gear...lol

Thank you... I always like to share when I think I have something worth sharing. In hopes to give ideas and to get feedback also.

Could come from low tire pressure in the rear tire also. Not that the tire pressure was noticeably low. But low enough for the tire to flex enough at that angle.
I do know the swingarms that I have selected will be strong enough. Since they were designed and built for much heavier/bigger bikes. With that said also presents a bit of a problem for me. Since I'm also concerned about weight.
So I decided to go with the xr250 rear swingarm. It's is the lightest of the 3. Plus it is just as strong so I'm happy about this.
I had the cbr250r swinger already to do some work to it. But I just couldn't because I felt the need to go with a lighter swingarm.
To some pics for visual....I will be cutting the xr250 swinger down some. Where the original axle goes through. Then make new slotted axle holes. The axle adjusters will slide inside the swingarm with end caps.

Almost forgot,this is the track I plan on going to when the bike is finished. Should be a lot of fun...lol

Coming together slowly.

You are building a real beast.

Thank you.. This is what I'm hoping it to do....
On that note, slight correction swingarm is from a yz250 not xr250. I had xr250 on the brain when I was searching..
Gonna use the cbr250r rear shock linkage... Got the rear wheel coming in soon.

[S2wheels]

DB swingarm with cbr250r tire fender.

Also forgot I bought some racing headers.
I did mod up some stock headers. To convert a 2 into 1 setup. I felt that they wouldn't have worked properly. So I stopped working on them. Plus the stock headers had some weight to them.

How the project going any updates?

[lineman55]

Wow, you are talented. Impressive project. Bravo

[S2wheels]

Thanks and no real updates... Work has been taking up a lot of my time. So whatever time is available. I do a lot of searching for parts that I can potentially use.
I really need/want to get this right the first time. So I do not have to go back and make major changes.
I did ended up buying new hubs. Instead of modifying the ones that came with the rims or making my own. Got in some rear shocks springs, brake calipers, front radial master cylinder, steel braided galfer lines and double bubble windscreen. Some reason I don't know why. I am most proud of the windscreen.

Plus I've been doing work on 1 of my other minis. To get it ready for some track time. Then I accidentally bought another project which I have to build.
Bought a Honda nsr50 for a fellow racer. And well the chassis is still sitting in my garage for over a year. So I have to build this thing too. I'm pretty sure the guy whelched on the deal...
But here's some photos.

Started working with some forks today. I was working on a set/modifying them. Got a little ticked off so I went a set of adjustable dampening ones I had on hand. I still have to MOD these up some. But I am loving the look and the lower front-end. This is what I was gonna do when all was said and done. This is the ride height I want for racing. Still good for street if I can get it tagged.

These side view proportions are actually looking good. Can't wait till you register it as a 50cc scooter.
