I also purchased a Hensim 250 from Tim recently after reading your review. I got it all put together and it rides great. Only thing that I don't like is the fact that I have trouble getting it above 60mph. It said 75+ mph on his specs depending on the weight of the rider.... I weigh 145. So, I'm a little disappointed there. My 200cc Lifanoid that I recently sold got up to 62 mph. Anyway, not a huge deal. I guess my question to you would be; when purchasing a 17 tooth sprocket from ebay, do I need one for a 420 or a 428 chain? I would really like to gain some highway speed. I took it for a ride on some forest service roads here in So. ILL and had a blast. If you could help me out here it would be much appreciated!
