What is considered high mileage for an Aprilia RS 125?
Significantly more than 4,000 miles per year might give me pause for thought. Try to look in the owner’s garage, is it clean, does it have race fairings hanging from the joists. Ask the seller what the warm-up routine is, what kind of 2-stroke oil they use, what the service schedule is (check any kind of service history closely, add up the mileage figures and compare them against MOT certificates if applicable – if there is no service history – run away). If the owner cannot answer these questions convincingly I would walk away. It is also worth looking at the sump plug to see if it is drilled for lockwiring and the rims to see if the tyres are frequently changed – those are sure signs that a bike has been raced or regularly used on track days.
