Your build has come out real good. Can i asked how do you fit the 10t front sprocket ,its a taper shaft on your motor ?
Cheers.
Hi , the sprocket is a lill bite wider and yes is tapered but it works good enough. Its from a UK store , search for MightE. Some other good stuff there also.

Re: MH RYZ (derbi 50cc)

All the weigth gonna be in the midle of the bike and is also compact. Still lower center of gravity than original bike with full gas tank. I reckon the bike will weigth less then 70kg.
21700 samsung 40t cells? They are avaiable in nkon.nl store.

Re: MH RYZ (derbi 50cc)

I used a stick welder with 3.2 mm electrodes at 110amps. Order already some 2mm to try. The welds was not finished and clean. I think the mig is probably the best option.
