Here are the crowns with Ø94mm hub hole from CHARVIN Industrie for MBK 41 / 51 moped. With the choice of 52, 56 and 56 (black) teeth models, you will be able to fine-tune your transmission settings. A large crown will allow you to obtain more acceleration (also take into account the variation / clutch part) while a smaller crown will offer you an extension in speed to the detriment of acceleration / recovery!

It's up to you to find the right compromise according to your configuration. It is strongly recommended to change your chain and sprocket to start on a new transmission without problems. An excellent quality Made in France crown with a treated and machined steel alloy. An element intended to last over time, do not forget to lubricate your chain well to avoid friction between pinion / chain / crown (to reduce heating, wear, play, etc.). Model with 11 fixing holes in width 415.
Be careful to select the number of teeth before adding to the basket.
