The Tripper Fastback seat was designed by custom motorcycle builder Dave Perewitz to fit Paul Yaffe's Razorback extended tanks. The Tripper Fastback's sleek profile complements the lines of the Razorback tank and offers riders the ability to move further back in the saddle. This expanded vinyl cover features the signature, diamond-stitched inlay designs and a tapered passenger section that keeps the streamlined profile intact, while still providing a reasonable degree of comfort for 2-up riding.
