SURVIVOR
Seems that's the consensus with others too, every year they've gotten better for the last several years. I've toyed with owning one, I wonder what years were best of the last 5 if any?
Yours manu dates? Any particular years to dismiss as possible purchases?
I’d stick with 2014 or newer; mine is a 2018. Annie’s is a 2019 and they made some big changes:
CYLINDERS
Precision honing for consistent sealing of rings at high temperatures.
Improved surface preparation for cylinder bore reducing break-in time and increasing oil retention for longer cylinder life.
Cooling fins increased in surface area by 20% for improved cooling efficiency.
CYLINDER HEADS
Cooling fins increased in surface area by 18% for improved cooling efficiency.
Exhaust port reduced in length for decreased cylinder head temperature.
Optimized intake and exhaust ports geometry for improved flow.
Redesigned cylinder head covers with improved sealing.
PISTONS
Gravity cast from NASA 388 provides superior heat resistance compared to forged pistons.
Teflon inlaid skirt for reduced friction.
Hard anodized crown and top ring groove for increased high-temp longevity.
Manganese Phosphate coated compression rings.
Top ring face inlaid with high-tech plasma-sprayed Molybdenum, offering increased durability.
Phosphate-coated piston pin.
OIL CIRCULATION SYSTEM
Improved oil pick-up design.
Oil sump redesigned to maximize oil capacity without sacrificing ground clearance. Oil capacity increased to 2.6L.
FUEL INJECTION SYSTEM
All new EFI system utilizing Keihin throttle bodies.
Electronic idle speed control (EIS) improves starting and idle.
Throttle position sensor (TPS) for improved throttle response.
Fuel injector location has been optimized to spray directly at the intake valves for increased efficiency.
Closed-loop EFI system with increased resolution for better fuel efficiency.
System fuel pressure increased for improved fuel atomization.
New self-priming, in-tank fuel pump with integrated filter and pressure relief.
High-efficiency catalysts for reduced pollution without sacrificing power.
WHEELS
All three wheels (including the spare) now utilize the same hub and are fully interchangeable. The rims are now supplied by a new vendor are made from improved aluminum alloy with superior strength and finish.
