CBR250RR 4 Cylinder

Motor ini diproduksi tahun 1986 hingga 1996. awalnya motor ini diproduksi di jepang dan kemudian di Australia. akan tetapi motor ini ditemukan hampir diseluruh dunia. Motor dengan kubikasi 250 cc ini awalnya ditujukan untuk biker pemula, dimana rev limit RPM hingga 19000 rpm. dengan 6 kecepatan. Sayang Motor ini sudah tidak diproduksi lagi mungkin dengan alasan regulasi keselamatan. berikut histoy dari tahun 1986 hingga 1996.

Years	Model	Description
1986	CBR250 (FG) and (FG-YA) MC14	Twin front disks, single front headlight, bikini fairings.
1987	CBR250R (H) MC17	Twin front disks, still single head light, full fairings.
1988	CBR250R (J) MC19	Single larger front disk, smaller chain, twin head lights, fuel pump.
1989	CBR250R (K) MC19	Essentially identical to the R(J), except now had a speed limiter which was set at 185 km/h.
1990–1991	CBR250RR (L) MC22	A completely redesigned bike that had a new cast/pressed aluminum frame that gave a more aggressive riding position, gull shaped swing arm that was adopted from the NSR250R, higher rising tail, six spoke cast aluminum wheels and dual front 276 mm (10.9 in) floating disk brakes. These changes resulted in a dry weight of 142 kg (310 lb). The only feature that was adopted from the previous model CBR250s was the MC14E engine. This was slightly modified with a crankshaft that had 27.5 mm crankpins, up 0.5 mm from the previous 27 mm size. The engine also used a completely new set of VP carburetors that had smaller throats, reduced from 32 mm to 30.5 mm. These carburetors were fed by a vacuum operated pump for fuel delivery.
1992–1993	CBR250RR (N) MC22	Essentially the same as the RR(L) except for new paint jobs.
1994–1996	CBR250RR (R) MC22	Still very similar to the RR(L/N) but restricted to producing 40 PS (29 kW) due to changes in Japanese law. The restrictions were in the cylinder head, head gasket and ignition unit. Redline reduced to 18,500 rpm (from 19,000 rpm).

Honda CBR250R (1 Cylinder)

New Honda CBR250R

Motor ini diharap sebagai Suksesor Honda CBR250RR terdahulu, tetapi dengan pengaplikasian mesin hanya 1 Cylinder. Menggunakan basis mesin dari motocross Honda CRF250. Secara mesin identik tetapi dengan penyesuaiaan kebutuhan salah satunya penurunan kompresi.  Diproduksi di Thailand dan India, tetapi dipasarkan diseluruh dunia, termasuk eropa dan amerika, dimana ditujukan untuk biker pemula. Model Motor ini bisa dibilang keluar dari pakem Honda CBR dan malah menganut alur body Honda VFR1200. Dipasaran diharapkan dapat bersaing dengan Ninja250.
