Motor sprocket 11 teeth - narrow with O-Shaft for Motors with 10mm Shaft
O-Shaft sprockets are fastend to the motor shaft using a splint. This splint is also within the scope of delivery.
... narrow means that the width of the teeth are approx. 3mm.
Models from the new Taiwan series are approx. 4,5mm wide.
(it makes sense to measure the rear sprocket, since the rear sprocket is easily accessible.)
! Always order the motor sprockets together with a rear sprocket and chain when making a replacement !
Note: For all the older models (2009 and earlier), there are motor sprockets for 2 different motor shafts.
1) O - shape shafts with only 10mm diameter and completely round shaft
2) D - shape shafts with only 10mm diameter (the shaft is D shaped when looked at from the side) and the flat surface is approx. 4mm.
These motor shafts are not common. If you are uncertain, please send us contact us for further information.
