Here is an update on my big tire build (10inch over swingarm) with the body on...a few draw backs that they don't tell you about adding a big tire kit...
1. you can't run a regular exhaust, without fabbing a special bracket or having the tube bent where it comes out the lowwer fairing
this is probalby why most people run a sidewinder or a bozbro type exhaust on the big tire bikes...I tried on mine and the canister hit the swingarm due to clearance
issues
2. you have to be real carefull with chain clearance and tension or your eat up your rims
3. and this they deffinately don't tell you when you buy the kits, I know because I had a major falling out with the company I bought mine from because they falsely
advertised all their kits as being bolt on with out any needed modifications. If you go with the 240 size kit, you will have to grind out an 1/8 of an inch from the
inside of the chain-side frame rail to clear the chain.
3. they do and have been making Z rated tires in up to a 250 for a while now, I'm not sure about over a 250 though.
4. get the air ride system it makes a 300% difference in the adjustability and ability to ride a passenger, it also compensates for the extended swingarm that usualy is
done with a big tire kit, the extension actualy changes all the ride quality for the worse if you don't do a modification to the suspension to compensate for the extra
length.
