I"ll look for the listing I had for a shop that makes custom sprockets with Kevlar (I think it was)teeth. .. They may be willing to share info thru email.
I KNEW I had been forgetting something. ..
Anyways, here's the info on the guys that make Kevlar lined drive pulleys.
Haven't used one myself but more than one member of the iron butt tribe have recommended them to me.

A. Custom Pulley - To install any of the pulleys below on a factory installed belt drive 4 speed, a .062 in. spacer must be installed either in front of or behind the pulley, so the transmission pulley nut will tighten up. All pulleys described below are available in custom widths to fit your project bike.

B. Invalude - All splines on the Pulleys listed below are 33 invalude splines 1/2" thick and are 55 Rockwell. They fit from 1986 to 1993 factory 5 speeds. To install on 1994 through 2006, an early spacer and seal are required. Factory P/N OEM Seal 12050 and OEM Spacer-33334-85.
These Pulleys weigh between 2-1/2 to 3 pounds depending on the size and require no special locking devices etc. These pulleys do not squeal when wet and have phenomenal wear characteristics under sandy conditions. Far superior to any other pulley (especially aluminum). The OEM Pulleys weigh around 6 pounds and rip themselves apart due to inferior material (cast iron with a Rockwell hardness of only 30).

Special width narrower pulleys are available upon request (Extra charge).
C. Sputhe - These pulleys are available in a multitude of configurations. They have a 6 splined center and we make them in special offsets for the 5 speed in a 4 speed box, (the letter "S" has been added after the part number). We make them in 1-1 1/2" widths as well as narrower widths to fit different 5 speeds using the 6 splined output shafts. The 5 speed 6 splined looks like the 4 speed at first glance, however, the 5 speed shaft is larger than the 4 speed shaft. These are easily confused when a 4 speed is not nearby for comparison. We make narrow kits for the factory chain drive 5 speeds in the FLT and FXR models, that can be installed with minimal effort and no major modifications. When installing these narrower pulleys on these models the primary chain drive can be retained.

Part Number
Description
RWP-5-68
68 Tooth, 14mm 1 1/2" wide, fits all 5 speed factory belt drives. Softails require clearancing of the top mounting bolt on the belt guard. Swing arms require no modifications. This Pulley is also utilized in many retrofit project installations as well. 5 speed wheel must be used. 68's are available in all styles.
RWP-4-68
Same as above except the 4 speed is offset .300" further outboard than the 5 speed. This Pulley may be used when wide tires are being installed on 5 speeds. This Pulley will adapt directly on all 4 speed factory installed final drives. No modifications required.
RWP-5-66
66 Tooth, 14mm Rear Pulley fits all softails from 1986 to 1989 with only a few minor steps. Some earlier softails will also accept this Pulley. You must be able to move your axle back 3/4" to adjust the belt. If you don't have the room, then a 128 tooth belt must be installed to accommodate the smaller Pulley. Will fit most 5 speed Swingarm Frames. This Pulley is available in all styles.
RWP-4-66
66 Tooth for 4 speeds require a longer than stock swing arm. Pauchco has these longer swing arms in stock, or one can be modified easily by almost any frame man. This Pulley may be utilized in many custom applications as well.
RWP-5-61
61 Tooth, 14mm, fits all 5 speed factory Big Twin final drives. This Pulley may be used to slow the engine dramatically. Under only a few cases can this Pulley be used. A large engine will pull this high ratio, for stock displacement engines this will be much too high when used with a 32 tooth Transmission Pulley. A belt change will also be required. "Softail" models require slight modifications to the top belt guard bolt. Outer flange designs are limited to plain, (chrome or un-chromed), floater, or chrome and slots. These Pulleys are also available in narrower than 1 1/2" widths. (Extra charge for custom widths)
RWP-4-61
61 Tooth, 14mm, Pulley will not fit on the 4 speed factory installed final drive as there are no belts available under 126 Tooth for this Pulley, however, many Sportsters use this Pulley. This Pulley is 1 1/2" wide and is available in narrower widths. (Extra charge for custom widths). Limited flange designs available as above.
RWP-5-58
58 Tooth rear wheel Pulleys are available in 1 1/2" wide, 14mm. Center distances should be discussed and what the resulting gear ratio depends upon what Transmission Pulley is to be used. This Pulley is used on many custom as well as early factory Rigid Frames. (Narrow Pulleys extra). Available designs include chrome, and slots, the "Wrath", round holes, and the Avenger. Flanges available include, plain or chrome slots. These Flanges are very narrow and there is limited room for design machining.
RWP-4-58
58 Tooth, 14mm, 1 1/2" same as above except this is for a 4 speed. This Pulley is utilized on many final drives. Factory Rigid Frames, FXR and FLT SuperMax conversions as well as 4 speed Sportsters. (Sporty uses 1 1/8" wide for use on factory installed rear drives). Designs available are the same as above (Narrowed Pulleys extra)
