The stock gearing of the MC22 consists of a 17 teeth front sprocket, 52 rear sprocket and a 428 pitch chain. The existing sprockets were far too worn to use again and after looking at alternatives a 520 pitch conversion seemed a viable choice with lots of sprocket options. I decided to go with a 14 tooth front sprocket paired with a 53 tooth rear and change it in future if it's too ridiculous, this combination provides quicker acceleration while sacrificing top speed.
The front sprocket is a SUNSTAR 14 tooth paired with a METALGEAR 53 tooth rear sprocket and QX-RING 520SRX2 chain.
