Quotation: @MIFIA4wrote on 1 May 2016: New thread ! MIFIA, no one has said otherwise !! It was claimed (and also scooters must therefore have one) ” !! And THAT can not be left standing SO, because otherwise this “wrong message” would spread!! But if you look at the Vario, then this is only a “reduction/reduction gear”, about in the middle the speed 1:1 from the crankshaft to the clutch is transferred, towards the end the clutch turns takächli ch far faster than the crankshaft !! And these high speeds must be the “reduction gearbox” to a moderate speed corresponding to the tyre size and engine power (that’s why also “reduction gearbox” THAT is actually the only task of these scooter gearboxes. Also a “studded diploma screwdriver” should know that there are quite several correct designations for the same thing !! …and that with the scooter 2 “angle gearbox” NOT GIVES (not even meaningfully) a d enkender man also know !! (Angular gearbox is what was called here as “differential gearbox” on the motorcycle) A cardan shaft on the motorcycle must e.g. have an “angle gearbox” on the rear wheel axle ! “Reduction gearbox” is therefore a quite common designation, not only for scooters. While “differential gearbox” for this “roller speed reduction gearbox” is completely FALSE !! (also on the motorcycle, even on all single-lane vehicles) !! kbw
