This brings up a question - I'm looking to replace my wheels - does wheel offset have the same affect as spacers? To keep the track width even, front to rear, 6+1 front and 4+3 rear seems to be the offsets of choice for the Talon. Will this have the same affect as spacers? TIA
Basically yes. For instance, a +50 mm offset wheel with a 40 mm spacer (for an effective +10 mm offset) exerts the same leverage on the hub as a +10 mm offset wheel.
But be careful, X+Y back spacing for UTV wheels is not very accurate. For instance, a 6+1 labeled wheels range from 45 to 50 mm offset and 4+3 labeled wheels range from 0 to 15 mm offset so don't go by the X+Y number, use the real metric offsets to be more accurate.
Because the rear stock wheel and tire are wider, you will need less rear offset (to move the wheel outward) than stock to achieve the same width front and rear. The stock front offset (50 mm) is only 12 mm more than the rear (33 mm) and the front wheel is only 6.5" so to achieve the same overall width with 7" rims all the way around, you need the front wheels to have 40 mm more offset than the rear.
Last I checked, there are no wheel combinations on the market that give you this exact 40 mm difference. STI has a 50 mm difference and System 3 has a 30 mm difference.
To get the exact same overall width front and rear, you can use 45 or 50 mm wheels all the way around and 40 mm (approx. 1.5") spacer in the rear.
So, putting the same width wheels all the way around and matching the width front to rear will put slightly more stress on the rear bearings but probably not much to worry about.
However, if you want width for some reason like duning, putting 0 mm offset wheels and 1.5" spacers on the rear will most likely be too much for the bearings. That is what my riding buddy did causing the failed rear bearings in ~500 miles.
Also note that no matter what wheels you choose, you will be wider than stock because you are going from a 6.5" wheel to a 7" wheel and from an 8.7" wide to a 10" wide tire up front. Even with the same/similar front offset as stock, you are gaining width by having wider rims and tires.
