Got my new belt. Can they be bent up to fit inside your factory tunnel bag?
I know the XS825 cannot.

No...don't bend them

Agree 100%. Timken says same - never do that.

Never heard you couldn't bend a belt to fit into a tunnel bag. What's the reasoning behind that?

The manufacturers warn about bending a belt so its backwards on its top surface in places. Apparently it can damage the cords and compromise its strength and durability.

I had a guy come in a few years ago with a two stroke Yamaha Viper and said it was hard to pull the rope - wouldn't start.
The belt was installed inside out....is that hard on the belt....?

Same thing I've heard. Can damage internal cords and thereby weaken belt. Also, do not wash belts in dishwasher, or lay them out in sun to "bake", or wipe with acetone. These were "old wives tales" that guys used to do.

You can. Just not Ultimax, Redline & G Boost, to name a few.

Some brand of belts will actually break when bending them backwards. Had it happen a few years back with the Dayco XTX belts on my old 1200, you could take a brand new belt, flex it backwards and it would break the cogs right out of them. They were good belts early on and lasted great, and then something happened with a compound change and they would chunk out the cogs right away. Early ones were fine and the latest batch would break right away, haven't bought a Dayco XTX belt since that debacle. They'd crack at the cogs and chunk out.

You can tell that the stiff belts that don't want to be bent backwards. If I'm not mistaken Timken Ultimate XS and the Redline caution you not to bend backwards. The 8JP could care less about being bent backwards, but myself I'd still never do it knowing what I know now.

The new mid size tunnel bags should be big enough to put a belt in without bending backwards anyway. The early Procross, not so much.

Ok guys, when you're done laughing...
I fold up an 8jp in tunnel bag, then I have a very small backpack. It fits a belt nicely & any small tools and parts you can possibly think of, including small bottles of boostane. Great for clutch tuning on the fly.

Maybe it's Monday thing, but I'm trying to wrap my head around how you guys carry a spare without bending it? Unless you have a big azz tunnel bag.

I carry an 8JP as a spare since I have been using the Redline as it doesn't seem to be an issue bending it.

The medium bag will hold a belt nicely.

That's what I have but the belt doesn't fit straight lengthwise. I'm really not that concerned, it's just funny I learned something new today about the belt I've been using and storing for years....lol
