[QUOTE=Paintwerks;1687060]I think there was some custom spacer requirements on Shawns' (Garth's) bike.

The Gen 3 wheels look better admittedly, but they are heavier by about 500gm per wheel. Personally, I'd either get BST Carbon wheels, Marchesini/Carrozeria wheels.....or leave the stock wheels on. But I wouldn't fit Gen 3 wheels.[/QUOTE


Paintwerks, plz correct me if im wrong but does 500gm = 1.1 lbs per wheel? If so that is not a big deal for me considering I have removed a few lbs off my bike from stock. I like the look of the Gen 2/3 wheels over the Gen 4. Is that the only thing that has you frowning on the swap? Just curious. I value you guys opinion on here and dont wanna regret something else in the future other than a total of 2.2 lb increase. Thx in advance.

Frotns will bolt right up... the wheel speed sensors come off of the wheels seperatly so you can bolt them right on and the 11's also have the same rotot bolt pattern, they are 310mm fronts.

on the rear you will have to run the 04-10 rear axle and the axle adjust plates to keep the wheels centered. you will also have to get a smal spacer for the inside of the brake caliper bracket so that the bracket will stay center as well, you can even make a spacer for inside the swingarm if you wish to keep everythign center but the axle blocks should keep it where it has to be.

OR you can attempt to swap out all the bearings to fit the larger axle.

Good luck!

Thx Garth. I am just tired of the 3 spoke design. Ive had it on all my past bikes and Im ready for an inexpensive fix. My budget does not allow room for Marchesinis or BST's nor would I benefit from their features since my bike is just a commuter and a weekend hobby.

I have just got hold of some gen3 wheels.
Was thinking of having them on the road coz they look nice and use my gen4s for track with track rubber.
So can i make the gen3 rear a straight swap somehow?
On another site they say the offsets are different.
Is that true?

You'll need a few things to make the Gen3 rear wheel fit. Gen3 axle, Gen3 axle blocks, Gen3 wheel spacers, Gen3 cush drive, modified Gen4 rear caliper mount with axle ID reduced for smaller Gen3 axle, Gen4 wheel sensor.


Front bolts right up with wheel sensor and correct rotors

Well ive been doing some measuring up today and the front will fit but the discs are 1mm further appart on a gen4.
The rear does have different offsets and i though id just stick the gen4 carrier on the gen3 rim but although it fits ok the offset is 2mm different on the carrier.
The wheel offset on the carrier side is 2mm different aswel so if you run gen4 carrier on gen3 rim it will be 4mm out of alignment which is a bummer as it would solve the bearing diameter if i were to convert all to 25mm spindle.
So you ideally need a gen3 rim and carrier to keep the left offset the same.
The right offset is different too as the brake disc doesnt sit in the same place.
I cant remember the measurement off the top of my head but im sure it could be got around.
So to me i need to have them fully assembled and weigh them with the spindles in as they dont seem like they are much heavier if at all.
Ideally i would have liked both rims being made the same diameter to make wheel swaps easier.
Below is a pic showing 2mm difference in height from left gen3 carrier and right gen4.
Height of bottom of sprockets is different and the bolts are sticking up higher on the gen4.
All measurements are carried out using vernias but not 100% as ideally i need to use my height guage at work for perfect measurements.

Ive decided against fitting the gen3 wheels. It can be done by modding the brake bracket and making custom spacers but it wont be interchangeable with my gen4 wheels without changing the bracket each time. They are slightly heavier too. . This seems to be because the center of the outer rim is thicker and stronger so better for road use it would seem

I had the Gen 3 rear wheel machined to fit Gen 4 wheel bearings and just swap the cush drive between the two. It fits great with no issues.

This was my intention but the rear wheel offsets are different.
The rear disc and traction ring are about 2 to 3mm offset compared to a gen3 rim.
Also gen4 cushdrive in a gen3 would make the chain run off center by a fair bit.
Its closer with gen3 cush but thats 20mm id.
If you have managed to line all that up then your wheel is running offset.
If all offsets are different then not everything can be in line!.
My opinion is its just too much work to get it spot on.

I had this done over a couple of years ago and got most of the info from a previous thread on the topic. Someone posted a schematic with measurements on how to make it work. I also just installed my Gen 3 rear wheel, and made sure not to make any adjustments to the rear brake pads (I usually spread them apart to make it easier to install the rear wheel). The wheel spun with minimal brake rub. I also took a couple measurements from fixed points on the swingarm and was within thousands of an inch to the Gen 4 wheel. I don't have an accurate way to measure offset myself, but my experience is everything lines up. If you don't think it will work I understand, it seems like you've put a lot of thought and research into this, but if you don't want to give up and need anymore information as far as measurements (I'll do the best I can) or pics just let me know.
