Off the wall question that I can't seem to find the answer to online anywhere... But does anyone know what the wheel bore size is on these units?

I acquired these wheels with my 2004 Bruin 4x2. They bolt on fine, no issues there, but the rears tuck in and the RH side actually contacts the muffler a little bit under suspension movement, so I'm wanting to throw some spacers behind them to bring the rear track width out some to at least match the front...

Thanks!

 

Welcome to the forums.
Quick search doesn't bring back a size. I'll try a more extensive one tomorrow.

 

Yep, trust me I tried before just creating a new thread lol

Thank you

 

If all else fails, I'd say a cheap digital caliper from Harbor Freight would be the next step.

Still looking.

 

Closest I've found is wheel spacers that have a 74mm bore, but say they fit than more than just Yamaha, so I'd be leery of that being exact.

 

On GrizzlyCentral, most who have grizzly bikes are going to xxbillettxx on ebay to buy machined solid spacers, seems an upfront seller on ebay.

Yamaha seems to use parts from bike to bike so what works on a 2004 Grizzly 660 "may" work on your 2004 Bruin. Worse case is ask the seller and see what their response is. Obviously the wheel lug spacing is the same.

 

Well I ended up getting a pair from a buddy to try on. He got them and then ran into the issue I was afraid of, having the hub-centric ring on the spacer being too big for the wheel to fit on. So he never even used them.

The paperwork with the spacers claimed that the lip on them was for a wheel with a center bore of 74.1mm. Turns out that these Grizzly wheels must be just a hair larger. They fit over the lip with a little wiggle room so spare, so I was able to bolt them on and use them

Looks much better and actually feels more stable now with the rear width matching the front.

Plus I was able to pop the original center caps for the wheels on since they came out far enough pass the original little rubber cap on the end of the axle to give clearance for it, and I threw on some fresh shiny lug nuts too. They're probably the only thing on this wheeler that's shiny right now, can thank my wife for that LOL

 

If it puts a smile on your face, you're doing it right!

 

This Bruin and our smaller Timberwolf keep my wife and I grinning from ear to ear every outing

I got the Timberwolf specifically for her because it's smaller and she's a pretty small gal (granted the Bruin isn't a hole lot bigger), but now she likes driving the Bruin because it's easier lol, no shifting... But I don't mine riding the Timberwolf. I'm not a big guy either, and it's 4x4 so I can have some fun in it too
