RZ250 Custom 350cc Top-End Engine, Running w/ Papers, Sevenstar Wheels, BEET Parts

This is a Japan-market Yamaha RZ250 that has been built up with a 350cc top end (cast with '350' marking) and comes with transfer/deregistration documents. The seller states it is being sold as a race/display vehicle and is not street legal as configured; it would need structural modification registration to be road legal in Japan, and is intended for track use only. Modifications include Sevenstar cast wheels, dual front discs, custom handlebars and turn signals, a three-step (stepped) seat, a kicked-up tail section, possible BEET parts (tail, alfin-style covers, fender, engine cover), and a megaphone-style expansion chamber exhaust. The seller confirms the engine starts via kickstart with no unusual noise. Prior to listing, the throttle/clutch cables, battery, tires, and front fork inner tubes and seals were replaced. The engine casting numbers are stated to be genuine/original.

Seller notes visible scratches and dirt (傷や汚れあり) consistent with a used bike, plus a malfunctioning horn, a faulty oil warning switch, and a carburetor that needs adjustment.

Shipping: Seller offers transport via Redline or BAS carriers, with a drop-off fee at the Kashiwa depot; the stepped seat ships separately via a standard parcel courier. As a complete vehicle, overall shipping/freight will be arranged separately from this listing.
