The GN250 started life in 1983 on the back of the revival of the 250cc singles and was given the custom styling. Despite it’s limited appeal, it has stood the test of time and is still in production in 2005. The engine is robust and features a 4 valve head, where the two exhaust ports vent to a two-into-one pipe with megaphone exhaust.
The front down pipes comprise of a small bore pipe running inside the larger chrome outer pipe, which can only be to reduce noise, but does make the exhaust system expensive to replace.
