Overall Width:
Typical around 45-48 inches.
Track Length:
RMK models typically featured longer tracks (e.g., 133.5" or 136") for better flotation.
Dry Weight:
Estimated 475-500 lbs (dry).
Oil Change Interval:
Refer to manual for specific recommendations, typically annually or per manufacturer guidelines for 2-stroke oil change (autolube).
Clutch Inspection:
