So far we haven’t heard anything about a hopped-up version of the Cleanfire 600 2-stroke already offered in the 2015 AXYS Pro-S.
Although there were some changes to this 125-hp mill they were not changes focused on adding more performance.
Basically, the only differences were new crankcase castings that feature the same engine mounting as the new 800, a new electronic oil pump that Polaris claims meters more precisely and cuts down on oil use and a new bypass thermostat that lets the engine control its temperature more accurately so it can max out its computer mapping.
Those changes may deliver a cleaner running engine that has more responsive spool-up.
The lighter weight of the AXYS chassis will no doubt add to its overall acceleration and maybe even its top speed performance.
