Belt drive conversion!?

I have seen on YouTube that some folks in Japan are running this conversion. I don't hate the chain maintenance on the CT125 enough to want to convert it. IMO the kit would do well paired with a belt enclosure to keep stones out, and a belt roller tensioner. Belts are great between two cogs that are always the same distance apart, like electric motorcycles where the front cog is at or next to the swingarm pivot, or the primary drive between engine and gearbox on Harleys. Something that's a pain on bikes that aren't designed for belts is that you often have to partially disassemble them to install a belt. Keep in mind that a chain can be broken and then made into a loop again with the master link attached, a belt cannot, so you have to maneuver a closed loop into place.

The belt on my Harley has given me years of trouble free service. No oil mess, quiet and the tension is only adjusted when the tire is changed out. I wasn't too sure about it when I got the bike 13 years ago but I'm sold...........for street bikes. I would put this on the ct in a heartbeat if I never took it off the pavement but a pebble can destroy a belt if it gets between it and the pulley.

since the frame sits inside the swingarm pivots on this bike, its much easier to do on this. me? id never do it. Shaft drive conversion would be way more interesting.

That would cost a couple bucks and eat up a horse or two at the rear wheel. Be smooth and strong though.
