MOPED ARMY

well the fastest is a variated bike but those are not the cheapest

the one with the most and cheapest performance options is a puch

since puch kits will work on a tomos those have a lot of kits also.

and if u happen to have a welder any performance exhaust will fit that puts all bikes = there.

carbs are a pain to mount on most setups not all but a lot of them. it is usually the hardest with tighter engines (most Japanese) or moving engines (moby and pug)

sachs have kits, but they do not have good clutchs. so they usually break after they get kitted, lol.

Peugeots and motobecanes can also be made very fast. Tons of parts for them. But theyre expensive and kinda hard to work with.

To answer your question, puch is the easiest.

-Puch / Tomos...parts everywhere. easiest by far

-Motobecane / Peugeot / Vespa / Derbi...bunch of parts too

like whats been said..not cheap and hard to work with

-Garelli / Minarelli / Morini...parts are out there, but you have to

look. some are harder to find since theyre no longer made.

Batavus / Trac / Jawa..I have never seen anything aftermarket
