The 1991 NSR Honda released a new model of the NSR. It was called the SE and now there were three types of models for sale. The standard model was plainly called the 250R model. It was available in only black with grey and silver accents. The R type was priced at 620,000 Yen and did not include the extra options as the SE and SP models. It was a lower cost alternative to the more expensive models and some people didn't care for the noisy chatter of the dry clutch. This was the first year for the SE ( Super Edition ) model. It was available in only one color of fighting red/white with blue and green distinguishing it from the regular R type model. The SE was priced higher at 660,000 Yen. The SE was made available because of the high price and scarceness of the SP models. SE version NSR's had the very cool dry clutch and the adjustable suspension for the front and rear plus SE markings. The SE was not sold with the light weight and expensive magnesium wheels due to the high cost. Honda continued making SP models for the street but they were pricey and limited to a few units. The 1991 SP was sold in Pentax racing colors, it had the light weight and highly priced Mag-Tek magnesium wheels which were made by Enkei, fully adjustable suspension for the front and rear plus the dry racing clutch. 1991 SP's were priced at 719,000 Yen. Production was limited to 1500 units so getting your hands on one of these will be tricky and probably pricey.
