Final drive belt upgrade

Does anyone know if Gates or anyone else for that matter is offering the new style narrow belts that are strong enough to hold up on big inch builds pushing 140/140. I'm trying to avoid what is probably inevitable (chain drive). Anyone got any part numbers etc? I know on the earlier style, the MOCO offered a heavy duty belt that some refer to as a sidecar belt but the local dealership I get parts from says there is not one for the narrower style belts on late model bikes with the wide tire. I was also told that Gates offers something called a blue line belt or something like this that is supposed to be much stronger than stock but I haven't found the time to call them during business hours. Anybody have any experience with these belts?

Why not just go to a chain and not have to worry about it?

Because of all the reasons chains suck. They are messy, require more adjustment, need to be replaced more often, etc., etc., etc., etc...

Gates GREEN Belts is what you were refering to.. They are stronger and more wear resistant.

Belt vs chain

Been there, done that... switched back to belt from chain .
Tried the Gates narrow belt. Two weeks, tensioned correctly. Snapped like it was a rubber band when I hit it at 2,000 rpm in first.
Went to the 1.5" "sidecar belt" from Harley and the required rear pulley change, no issues.
Bottom line, in my opinion, which may not be worth much, if you have lots trq and HP, AND you want to actually use it below 30 mph, the skinny belt will not cut it.
Probably going to get responses about how guys have more hp/trq than me and no issues... Well, put my fat ass on your bagger, let me have the clutch fully engaged and see what happens when I smack the throttle WFO at 15mph... Bottom line, chain or BIG belt is needed for high HP/TRQ motors unless you want to baby them and
what the hell is the point in that??

I'm using a 1" Goodyear belt for the Buell 1125R on my bike. I chose it because the Buell puts down 130 HP. So far, so good, been on there over 10K miles. It has survived holeshots and wheelies just fine.

Have the Gates 1 1/2" Kevlar belts on all three machines.They are adjusted and checked often never worry about breakage,if one ever breaks it will get replaced.No more chains for this cat.The wife always reminds me of her new white jeans that were ruined the left leg was a wash with chain lube on a run one time
