The belt for a 78 ex440, is listed as 8F2-17641-01-00
Belt for a 78 ET 340 listed as 820-17641-00-00

might just be the hardness of the rubber. the et one would be softer. i know my et belt will work on my war to get me home as long as no wot hard running.l

Maybe if the ET one is softer, it would work better in my situation, for a oval racer. But if its not as strong belt that would'nt be good.

89X-17641-01-00 (replaces 8F2-17641-01-00) Not too sure of the original spec on the 8F2, but the 89X thickness is .5mm shorter and the angle of the belt is 4* smaller.
This is compared to the 820.
