150cc beast
i bought one of these bikes the only quality issue i have is the rear shock
had 12mm hole /10mm bolt in frame,easy fix drill hole out replace bolt
the chain guide was a bit sus yet to re engineer.the suspension is awsome
as im 75kg handles every thing ive thrown at it.these engines can be improved in performance dramaticaly,remove spark arrestor, port head,shave 10 thou off head,port inlet manifold easy 25% increase full range of power.these engines are very reliable as i have reved mine so hard and tried to blow it up.stripped engine after 6 months and bore piston etc perfect,very durable.friend of mine has 125cc version and it revs harder.blokes racing 125 type getting 20hp havent dynoed mine.
height is great for 6 ft riders balance is good lots of fun can handle 3-4mtr jumps 1 to 1.5 mtr high no problems.i would like to upgrade swngarm which is steel one to alloy.great bike dont be afraid to buy one,the 200cc engine is same stroke bigger piston there fore dont rev as hard ,for 1500 dollars i reckon good value,pitties are a tad to small for me where this baby i can do 2-3hr rides no problems no discomfort.
