Anyone have experience with belt drives? Can this thing even change gears?

What do belts have to do with shifting?

Standard 5 speed. The belt replaces the chain. Less noise, less maintenance, and they last longer.

The belt drives the rear wheel. The gear changing magic happens with your left foot, where the arrow is.

Suzuki, that’s not savage. This right here. This is savage.

I know that, lol, but compared to chains I just thought that belts would be difficult to build a transmission around, considering how wide they are. But I guess not?

I’m not really a motorcycle guy, but they’ve got chain, belt, and shaft drive on bikes pretty well dialed in for function/assembly at this point. I’d be willing to guess a belt drive only adds about a half inch of width compared to a chain drive.

Harley uses belts on their normal production bikes exclusively I think. Not exactly engineering marvels but they’ve been doing things that way since the middle ages and they’re at least functional. The nice thing about belts is low maintenance; no need to clean and lubricate them every time you come to a stop. Saying a belt drive affects a transmission’s ability to shift is like saying is like saying the cup of coffee you had this morning is going to prevent you from having dinner tonight.

I own a belt drive (and 2 chain drives). Can confirm, it does not change gears. But that has more to do with the fact it’s a direct drive.
Belts work just fine. You can convert any chain final drive to a belt with a couple pieces of hardware.

it’s no different than a chain drive, the transmission output shaft just has a different style of sprocket. Motorcycle drive belts are basically the same as engine timing belts in cars.
Chain drive sprocket:

I think some people conflate belt final drives with the rubber belt CVTs in a lot of ATVs and other powersports vehicles.

Bike transmissions are packaged very differently than a car transmission. The slight added width of the belt is not too significant. It is often used to help smooth out a drivetrain and reduces the need for maintenance compared to a chain. Shaft drive requires even less maintenance and checking, but they can be a bit harsh when coming on/off power. CHains are the strongest power delivery method and by changing the sprockets at either end of the chain you can effectively modify the “gearing” a bit. But they get dirty and need very regular maintenance.

Belt drives are standard for Harley Davidsons. They’ve been around forever.

Harley has been using belts since the early 80s. Victory, Indian, and I think some of the big Yamaha cruisers use them too.
Belts not new or unusual.

I find it weird that someone with an understanding of how CVT works would make that assumption.

You forgot Buell (just like the motorcycle industry itself did).

or confusing it with bicycle chain drives with derailleurs.

That’s what it was, I don’t (didn’t-after now I suppose) know how a motorcycle trans worked but I thought the belt would shift or move within the transmission but yeah nvm.

a motorcycle transmission is usually just like the manual transmission in a car, except with a different style of gear selector mechanism to enable a sequential shifter instead of a gated one.

Thanks for following up. Your question makes much more sense now.

Lol virtually all Harleys have belt drives. Always have.
