Engine:
The engine has been changed (original 88 ci still left and OK as well); it is a 95 ci version. Especially when riding two-up, you can notice quite a big difference both in torque and power.
Suspension:
Front has progressive springs, rear shocks have been changed to Progressive units as well. Air is not used anymore, works well just as it is.
Wheels & Tires:
Original wheels, still...
Body:
All original except a lot of chrome added wherever applicable.
