I'm planning on getting a 2 stroke 66/88cc kit with a SBP jackshaft and i want to basically have a mini dirt bike. I'm looking for a base bike that's 7 speed and maybe has fat tires. If anyone's ridden in loose dirt with a normal mountain bike vs a fat tire your opinion on whether a fat tire is necessary would be greatly appreciated. Basically looking for a good starter bike that's not 400 dollars. Thanks!
