internal belt drive pros and cons
#11
belt or not
Harley briefly produced a model with belt primary, the Sturgis, but didn't stick with it. I don't know why, but frankly a lubricated and enclosed chain is pretty hard to beat, as a way of transmitting power. The Harley drive train is fine IMHO. Find something else to spend your money on!

Been running belt drives since the 1970s; even had a Gilmer belt (square teeth) on a 77" stroker 1972 XLCH, and it ran in an oil bath. I've broken 1 belt in all that time and that was because I didn't vent the primary on my '78 Shovel. I've put nearly 400,000 miles on 3 different bikes, and a total of 4 belts, with primary belt drives.
Is a standard enclosed drive going to hold up to a big inch/high HP motor? Nope, and none of the manufacturers claim that.
Lighter, less vibration, no oil to leak - works for me...

Except that I have a 1-3/4" on a 1987 Sloptail that has about 100,000 miles on the belt. The key is ventilation. My outer primary is basically cut away so that it is a shell; enough there to keep my pants leg out of the belt, to provide support for the starter solenoid and its works, but otherwise open.
