The 1994 NSR MC28 model NSR went on sale in Japan as a 1994 model. It was completely different than previous models and changed peoples thinking about two stroke technology. The new Proarm NSR's as they became known in Japan were the ultimate 250 bike for the street. They had PGM IV technology which allowed more accurate control of the carbs, smooth operation and perfect driving manners unlike past two stroke bikes. The all new Memory card replaced the standard key and made de-restricting the bikes very difficult.

The 1994 lineup saw three types of NSR's for sale once again. There was the standard 250R type model in fighting red and Ross white. They were sold with a regular wet type clutch and non adjustable suspension. They were priced at 680,000 Yen.

The SE model was priced at 720,000 Yen and came with the fully adjustable suspension front and rear made by Showa plus the dry clutch and different colored front disc rotors. SE colors were the same as the standard R type in fighting red and Ross white but were marked SE and the NSR logo was in bright yellow. SE models also were sold in blue and white with orange accents and also were marked SE but the NSR logo was white. 1994 also saw the return of the Rothmans colored NSR's for the SP models only.

They had all the extras as previous SP models. The MC28 SP bikes had different front fork adjusters with cool blue anodized blue knobs, the same gold colored front disc brake rotors as the SE model and were fitted with higher grip and more pricier Michelin TX11B and TX23B sport tires than the SE and standard models. The price was a whopping 800,000 Yen for them and only 1,500 SP bikes were built by Honda. This was to be the last year for Rothmans colored NSR's ever. Today finding a Rothmans SP is quite rare and expensive due to there limited numbers. Honda was changing two stroke history with these latest fifth generation model NSR's.

They were very expensive but for the technology they had were reasonably priced. The memory card was very slick but some what controversial because of the difficulties in de-restricting the bikes, but those cards looked cool and it started a trend for others to follow with it's digital speedometer. The bodywork also had been upgraded too for sleeker aero dynamics and better looks to match the all new single sided swingarm or simply PROARM. Power was down to 40 horsepower from 45 on previous NSR's, but acceleration performance was not hurt.
