Kestrel Take

The modern stand-up king — the SX-R 1500 revived the stand-up class with a big four-stroke, making it powerful, torquey, and (relatively) approachable compared to old two-strokes. It's a specialist toy for skilled riders who love the stand-up experience. These get ridden hard and dropped, so inspect closely. A low-hour, freshwater SX-R 1500 with clean compression is a thrilling niche machine; verify hours, hull, and pump.
