Matt if your keen on a china thumper, arent the fastest rider out there, and just want a trailbike, then the Blitz isnt a terrible bike, it's just not great when you compare a stock one to a jap traillie, or even more unfairly, a bike like a WRF or CRF250x... they arent even in the same league aside from looks..
However, read the first page of this review if you want an idea of what a stock one is like...
Keep in mind, mine was worked off it's tits, cause i dont like stock bikes, it's performance was way below my liking (I'm an ex-racer with 27 years on bikes, not a beginner) and because i wanted to see how far i could take the thing... not because it absolutely has to be done to make a Blitz rideable..
Another bike to consider, is the X-Moto XB31 if you can find one... they're a bit cheaper, but they're also lighter, a bit less fragile, and the Gen II engine performs better than the stock Gen III engine in the Blitz... My missus has one, and stock standard is a much quicker bike than a Blitz..
