bgm PRO MRB Race-Tour 195/200 & 225/230 CYLINDER KITS 18. GEARING RATIOS

Gearbox Close Ratio

Gearing again is to some degree a matter of personal preferences. But there is a range that has worked for customers of the RT kits. This is from 5.20:1 down to 4.3:1. Our best all round recommendation would be a gear ratio between 4.94 up to 4.80. This suits most customers and riding styles and there is enough power thru nearly the complete rev range in fourth gear. If you ride most of the time two up and/or with luggage then you should consider choosing a slightly shorter gearing. If you don’t mind to ride in 3rd gear most of the time and use the 4th gear as overdrive or flat out on the motorway, you can opt for a slightly taller gear ratio than the 4.80. This gives a high top speed at low revs on ideal conditions.
