We now make four versions of our NSR250 GP Race seat cowling for use in 8 different race and street sets. This product includes ONLY the seat cowling for replacement in the event of an accident or to use on a model other than the MC21 or MC28. For the MC21 and MC28, we recommend ordering one of the complete kits below (BPFS-****) which includes all the necessay parts to complete the modification. BPFS-0003 (street) BPFS-0004 (race) uses BPFT-9002 MC21 with carbon front section BPFS-0059 (street) BPFS-0060 (race) uses BPFT-9102 MC21 all GRP construction BPFS-0004 (street) BPFS-0005 (race) uses BPFT-9012 MC28 with carbon front section BPFS-0045 (street) BPFS-0046 (race) uses BPFT-9112 MC28 all GRP construction The advantages of this seat cowling over stock include: – new design allows for integrated LED Tail light ( BPLT-0008) for flush fitment and new lighter registration/license plate holder ( BPFX-9006). For race use, location for LED Tail light acts as air vent – higher at the rear, to give the bike a more agressive stance – better rider control by use of enclosed seat area – improved strength with precision in design and fitment as well as lighter weight.
