My son is a new owner of a mx350

I live in canada, and finaly found a mx350 for my son, they don't sell it anymore in canada, because of the max 100watts law. So i found a 2008 mx350 with rear suspension, and i just changed the two dead batteries, with two powersonic 12v 9ah. Wow it was able to reach 28-29 kph(i was driving behind). I'll have to check for rear brake ajustment, or change it, but he is very pleased with is new ride. I readed alot on this forum about upgrading the bike but i think i will wait until next spring to do it. Is anybody as been able to import a mx500 or mx650 in canada?
