I think if your wanting to try that, as least a 150 cc frame would be a better choice.. The 50cc front end is pretty light, and not designed for sustained heavy loads... Fawkes as a stroker could do 60 MPH confirmed.. It put more stresses on the front end applying braking, and put more punishment on the front end rolling over pot holes.. I had to put a larger front tire on my front, and adjust my braking ( always applying both ) to relieve some of the stress..
without some serious reinforcing from purely a safety standpoint, I would not do it on a 50cc frame, something a little heaver Maybe..

A VOG 260 maybe as they were based on the 260cc Majesty engine.
A 30/40 mph sub 200lb bike frame and braking system is not going to hold up to a Majesty 400 power unit very well.
The Majesty 400 was designed for a 15 radial front tire and weighs over 400lbs and can easily carry 2 200+ lb people at interstate speeds.
You could also look for a Majesty 400 with a blown engine and be 100% there.

I would maybe try the conversion with a 250cc or larger maxi-scooter, as from 250cc on up they are about the same size overall. Doing the conversion from a 50cc aircooled engine to a 400cc liquid cooled engine means you are going to have a lot of things to make, convert and fabricate for it to work. Plus you have the disadvantage of the 50cc scooter being built really light and it may not be up to the task or stresses involved.
Also i would concur do not try to do this conversion to your regular everyday transportation ride, or you will be walking after you start the conversion.
But if this is a second ride then it can be a huge amount of fun seeing if you can do it and succeed with it too.

All I will say is this, my front forks are needing replaced, noticed the left one leaking oil, and a hair bit of play in both.. I believe this to be as a result of the stresses I put that front end thru.. I have 6855 miles on this frame and forks.. Far premature for forks to be worn out.. So before you attempt a project like this.. Give to thought to your safety, and that of others on the road with you, a failure of this nature would be catastrophic...

THe guy that won the Scooter Cannonball run last year took an antique Salsbury scooter that probably came with a ten horse power motor and transplanted a 250 Kawasaki Ninja motorcycle motor in it and he ran like crazy blowing away all the other riders in the race. Here is a thread on the build www.tnttt.com/viewtopic.php?f=49&t=50015I have to read that article - but on my 16" Xingyue, or another similar large wheel scooter, IF I had a shop and a little money, a ninja 250 would be an awesome upgrade. Make it shifter scooter with an easy 40hp stock. I've seen pictorials and video about that Lambretta with a Yamaha RD350 two-stroke... Never found anything to read. |

As a former Corvette owner, I can tell you that replacing a Corvette motor with another Corvette motor is something I would never attempt again.

Anything is possible with the right tools for the job. I personally think you'd b better off just buyin a frame or have 1 made for this motor. A 394 on a 50 frame could prob be done but that's a lot of motor plus it's not lite. I wouldn't do it
