Hey guys Im new here, hopefully ill be sticking around if you dont run me off with this question lol but I bought a United Motors 150cc scooter from a buddy to build for car shows to put around on. I want to stretch and lower it. I know how to lower it, but not sure the best way to stretch it? All I can think of is cutting frame and extending it and welding back up? Is that the only option or am I overlooking another technique? Any help would be appreciatedd  |

It's Dumb...
For one thing you could never register it and secondly, The front brake isn't designed to stop you at 50+ MPH and it's got 50cc forks and 50cc size. It's a death trap. Only ride it on a sanctioned track or a closed road with full protective gear and if possible take video so we can all see the wipeout. ;D

Awww, c'mon now Fox. You know my Venus is a small 49cc scoot that goes 60MPH with a front drum that's touchy and I'm big so it's probably REALLY not meant to stop the scoot + 280lbs @ 60MPH. It does OK though, and it's really fun. I will agree that stretching doesn't seem like the best idea to me for a street scoot, especially with those fat flat tires. I've rode with a flat tire to get home and you steer it like a car with the handlebars and can't really lean. I imagine that will be the same, though more stable. Kinda loses the point of being on 2 wheels when you can't lean to some degree IMO. That said, it probably would make a cool ride here and there. Now, all that said... welcome to the forum cadillac! :welcome: A fat tire kit and a stretch would be sweet for what you want to do with it. That kit is way pricey though, and wouldn't fit your scoot anyway since it's intended for 50cc frames. I think you're going to need to make your own motor mount to move it back. Here's a guy on another forum that made his own fat tire wheel hub from the old wheel and is in the process of stretching his 150cc. He cut the engine mount off of the frame and is going to fab up his own custom stretch mount. scooterrebels.proboards.com/index.cgi?board=showoff&action=display&thread=1092&page=2 |

To lower the forks you can either drop them down in the triple tree, sometimes impossible if the upper tubes have a slot in them, or cut the springs. Cutting the springs a bit doesn't harm anything, just makes the ride a bit stiffer.

Thanks for the help guys! Im not too worried about the fat tire kit for the back, just wanna extend it about 8-10" inches. I figured I could chop the frame and slide a slightly larger size metal over the frame rails and weld it back up while leaving the motor etc in place. Then extending any wiring or brake cable for the rear if necessary. Keep the info coming guys this has been very helpful so far! Also in TN this wont affect me registering it either.

Your plan sounds easy, but when you look at most scooter frames it might present you with some problems. Usually the floor is the only straight spot where you could do it. So then you are stretching the area between the front and controls and the seat. You'd need to construct a new floorboard and underbody. There will be more work involved in wiring too. If you stretch the engine out, you just need to worry about engine related wiring. Stretching up there, you would need to add in rear tail/brake/turn wiring, maybe the CDI and rectifier wiring (depending where it's located on your scoot), fuel tank sender wiring, etc... Could be cool, but I'm not sure if that's what you were going for. You really need to stretch the engine assembly back to get the look that most want, and that's gonna require more custom fab, so it won't be a sort of slip fit job so to speak.

Sorry if I offended anyone, I just think that 50cc frames aren't built for 150cc power and if they are a "bolt on" kit then you are asking for trouble. I think that kit is most likely illegal in many states.
That said, I'm sure it's fun and exciting and all. :riding:

I'm not offended. It's hard to make a distinction in what's a 50cc and 150cc frame. My Tritons are just like my friend's 150, aside from the engine mounts. A lot of scoots are available in 50 and 150cc with no major changes to the frame. Sometimes the 150s even have the crappy brakes and such.

I'm with ya Fox, I wouldnt ride one. At the bottom of the page it says "all conversion kits, wheels and tires are considered for show purposes only, and are not for highway use."
The poster said "show" so that site is what first came to mind.

Yeah I guess it's all a matter of choice and I'm glad we live in a country that gives us that option..., until enough bodies pile up then it comes down to a law suit and a recall. You are right Brent. My 4T 50cc scooter has the same basic frame as the 150 version. Same thing with 13 inch rims but they upgrade the brake on the 150.

GO CHINA! LOL 50cc:  150cc:  |

I think a stretch is good for looks only, or for a drag scoot. Thats just my opinion! They look killer!
Im still trying my best to keep my front end down without having to stretch mine. And if i do, i really like the way shakerdriver did his. He just welded an extra set of motor mounts on his frame and left the stockers. I like that idea in the fact that you can switch back to stock length when ever you like.
Then again, frame are different with different mounts and mounting positions so im not sure this way would work on all scoots?....
