525 Countershaft Sprocket
Highway cruising on your Modern Classic an get a buzzy at speed. Its ok to admit that you’ve tried to click up another gear when hitting the highway -- we’ve done it too. To make interstate travel a smoother af-fair, British Customs has engineered a lightweight countershaft sprocket that allows riders to easily adjust their gearing ratio.
Each sprocket is manufactured from 8620 case-hardened steel and CAT plated with lightening holes to provide reduced weight compared to the stock sprocket. The BC sprockets are visually appealing and made to last, meaning they look fantastic when exposed with the British Customs Front Sprocket Cover delivering a true hot rod look.
Going up one tooth from your bike’s stock configuration is a great alter-native for freeway riding and feels like you’ve added a 6th gear to your Triumph Modern Classic. Changing the number of teeth on your countershaft sprocket has the same effect as changing your rear sprocket by two teeth. Increasing the number of teeth of the countershaft sprocket will give you the feeling of adding another gear on the freeway. If you are looking for more get up and go out of hole, drop down a tooth. The lower the tooth, the faster out of the hole, more push off the line, and less top end (top speed).
NOTE: You are able to verify the number of teeth on your bike currently by removing the sprocket cover and counting the number of teeth. There are no fluids or gaskets required to remove the sprocket cover.
