The gear reduction provides a 25% overall reduction in every drive mode and gears 1-6 without increasing your width or height like the ever-popular portal boxes do. So since I have 30" tires, I'll still even be geared lower than stock form on stock tires with the gear reduction and not have to worry about the clutches nearly as much. 32" tires would put you about equal with stock but most are much heavier than the stock 26's, so probably a little under stock power levels with those. It will reduce your overall top speed, but that doesn't really matter to me anyway. If you kept your stock tires, tt would be like you changed them out for 19-20" tires if my math is correct.
@Scooterchris can tell you more.
25 percent on top of the 26 inch tall tire that comes stock on these machines (yes I know it says 27.) Is a 33. Now since we're taking some rotational mass off both the clutch and drive gear. Plus we rounded down on the actual percentage.
The p1k5 handled the 32's no problem
the test bike was running 32 inch outbacks at the end which measure a hair shy of 33 ran just like stock.
the IGR is gonna have better performance than your portal lift.
IGR 25 % vs portals 27.2%
IGR cuts weight off the drive gear and clutch. Allows to rev a little quicker.
portals add 200 plus pounds to your buggy, widens it, you have to go buy different rims if you're not running 0 offset already. And has alot more overall rotation mass.
A same setup portal lifted pioneer is a dog on 33's
