Here are the crowns with hub hole Ø98mm from CHARVIN Industrie (CGN selection) for all owners of MBK 51 S! With a wide range of 42 to 60 teeth, you can fine-tune your transmission settings. A large crown will allow you to get more acceleration (take into account also the variation / clutch part) while a smaller crown will give you a speed increase at the expense of acceleration!
It's up to you to find the right compromise according to your configuration. It is strongly recommended to change the chain and pinion to start on a new transmission without problems. A crown of excellent quality made in France with a treated and machined steel alloy. An element destined to last in time, do not forget to grease your chain to avoid the friction between pinion / chain / crown (to decrease the heating, the wear, the game, ...)
Be careful to choose the number of teeth before purchase. Only available width 415 with 10 fixing holes (see diagram below of 42 and 60 teeth).
