The Honda NSR 150 SP is considered an introductory-level motorcycle, and featured technology unprecedented before on such a small bike. This includes Honda's famous pro-Arm suspension, RC valves, and Nika-Sil coated cylinders. The model was designed with a "big bike" look, and featured Repsol colours in a tribute to Michael Doohan. It has a power of 39 bhp (29 kW) from its 150 cc engine.

An NSR 150 SP currently holds the Bonneville land speed record for production 175 cc motorcycles at 104.4 mph.



The Honda NSR 150 SP was to be the flagship of the Honda range of motorcycles; however, it did not have high sales within its intended market. The 2001-2002 models were introduced to the Australian market and have sold well.

For those readers unfamiliar with the NSR150SP, here is some background. It was introduced as an Asian model only in 1997. This model (KW6) like all the NSR150s before it was built by Asia Pacific Honda in Thailand. The bike was actually styled in Italy and the engines built in Japan. With Pro Arm suspension, RC valves, Nika-Sil coated cylinders, tacho, big bike looks and Repsol paint, it was to be the flagship of the Honda range at a time when Honda sales in Thailand alone were approaching 800,000 bikes a year!

Unfortunately, it was not a big sales success, due to its price tag and the Asian economic crisis. Sales by 2000 were on the slide and it was exported to Australia where it has been part of the Honda range there until recently.


This is the Honda NSR 150 RR which is built for the Thai market. Motorcycles are limited to 150 cc's in Thailand, so this bike was designed and is one of the ultimate bikes in Thailand. Of course you can buy bigger bikes, but these must be imported into the country and can be quite expensive. This bike is also popular in other East Asian countries as well.

NSR Racing History

For the past twenty years or so, there is one manufacturer who has been above all others in the premier class of grand prix motorcycle racing, and that manufacturer is Honda.

Winning 12 of the last 20 World Championship titles, Honda’s recent domination in 500GP and MotoGP has been a sea change for the series, and the company’s winning total in this modern era of four-stroke and two-stroke machines is double the next nearest OEM, Yamaha (MV Agusta still holds the outright record, with 18 championships from the 1956-1974 period of four-stroke racing).

Part of Honda’s success has been the fact that the Japanese motorcycle manufacturer has been able to attract some of the best riders ever to come to a Grand Prix race’s starting line, champions like Mick Doohan (1994-1998), Àlex Crivillé (1999), Valentino Rossi (2001-2003), Nicky Hayden (2006), Casey Stoner (2011), and now Marc Marquez (2013).

But also part of the equation has been the superb equipment that HRC, Honda’s racing department, produces for its riders, bike likes the Honda NSR500, RC211v, RC212V, and RC213V, which have widely been regarded as the best machines on the grid in each of their respective eras.

Looking down the pipe, as MotoGP adopts new rules and regulations, the RC213V and RCV1000R appear set to dominate their respective classes as the factory machines will be reduced to 20 liters of fuel for next year, and the open class machines are forced to use both the Dorna-supplied ECU hardware and software.

It would appear that Honda has a firm grasp on the next few years of MotoGP racing, and as a bit of an homage to this company’s fantastic two-wheeled craftsmanship, along with the racers who rode them, we give you wallpaper-sized photos of Honda’s Grand Prix motorcycles, from the 1995 to 2013 seasons.
