seen a couple in a guys truck heading into elk country last year, they looked new etc. with gun boots on side etc.
the next best option for a bush bike on two wheels would be the yammy tw200, it has a 14" rear rim and will take an 25-26x8-9x14 front atv tire on the rear wheel...or use stock tire and pick up a tire chain made for a front atv tire and pre-fit, may need a new chain to move the wheel back in its adjusters to have clearance in front of the swingarm however...pretty much a necessity if you put the atv tire on but i'm sure you'd have to do the same to use a chain for when things got ugly...oh, did i mention the tw200 is street legal too?
i have two bikes for playing offroad, a tw200 bushed out with a 26x9x14 bighorn rear, added kickstart, larger fuel tank etc. and geared it to about a 90 k top speed but its an incredible little bike, then did similar build on a wr250r i can hit 135 with but its for covering ground and exploring rather than hunting and bushing with...its the fun bike and it is way funner, but you can still cover ground quicker on the tw200 than any quad i've ever had...unsure yet on ability to haul anything out lol but you could throw deer over the passenger seat and ride out but i'd personally just drag a deer out, moose/elk would have to be quarter at a time maybe two, i have my tw200 geared low enough you can walk beside it without clutching, i am going to add an auto clutch so its like an atv also to add to its (half of an atv appeal)
