Part number 33112302420. Ratio 37:11. With 3 wheel bolts. A clean and fully functional final drive in very good condition. Late version as used in models from 1984 onwards. Also fits the models from 1980 onwards. Turns cleanly, is tight and has no objectionable play, no quirks or damage. Surface not blasted or machined. No typical enduro camber or grinding marks. Low mileage, certainly no longer available in this condition.
