Product Description

Ready for even more Mustang attitude and features… the Mustang 250 Evo3 is now here. The MY21 Mustang 250 Evo3 builds on it’s decade long history of punching above its weight class in respect to power, chassis and rider ergonomics.

We’ve removed the 2 valve power plant out of the Mustang 2 and dropped in a double overhead cam 4-valve beast. We then jetted the carburettor and replaced the steel rims with precision cast aluminium rims.

The updated Mustang 3 is now more refined than ever with the main focus on chassis development which involved tackling the limitation of the front end by adding fully adjustable ball joints to both the top and the bottom A-ARM. The adjustable ball joints add an almost endless flexibility in the camber set up.

We have focused on the power delivery and this led us to changing the carburettor design and customising  the jetting to better suit the individual characteristics of the Crossfire DOHC 4 Valve 250cc power house.

MY21 Mustang 250 Evo3 has been reinforced, redesigned and enhanced. This has been done by reinforcing all mounting points where shock absorbers connect to frame and A-Arms as well as swing arm. This bracing stops metal fatigue and provides a stronger more rigid frame. The new MY21 is lighter yet stronger than the model it replaces. The chassis has been condensed to improve handling and give the Crossfire Mustang the stance and stability through corners.

Hydraulic disc brakes all round are standard. The speedometer is one of the most comprehensive units fitted with: speed, odometer, distance, gear position indicator, as well as indicators for neutral and reverse. This gives the rider all required information at a touch of a finger tip. The automatic chain tensioner will ensure you ride days or week before adjusting of the chain is required. When one has to adjust the chain the ecliptic chain tensioning system guarantees the sprockets are in perfect alignment.

Under the seat some of the craftsmanship starts to become more apparent. Within a sealed battery box are housed the vital electrics keeping them clean and water tight. The new battery is an AGM gel battery which is maintenance free, long lasting and sealed so there will be no leaks. You can also see under the seat is a large sealed air box with a quick release wing nut that holds the air filter. The foam filter is quick to access to clean, re-oil and then reinsert.
