High-Tech Two-Stroke: 1996 Honda NSR250R MC28 for Sale

From the “jeez, if you’re going to post your bike for sale, couldn’t you at least wash it” files comes this Honda NSR250R MC28. Early NSRs have become relatively common on this site recently, with containers full of them coming over from Japan, now that they’ve become relatively easy to register in some parts of the US. But the MC28 version is still pretty rare here, as it isn’t yet 25 years old and is pretty much the ultimate development of the successful NSR formula. The MC28 features many trick parts, like the single-sided swingarm and Honda’s PGM-IV electronic ignition that interpreted throttle position, gear-selection, and rpm to create three-dimensional ignition maps for each cylinder and to adjust their RC “Revolutionary Controlled” Valve for improved power and midrange response.

All that technology served a 90° liquid-cooled 249cc v-twin backed up with a six-speed cassette gearbox. As has been discussed at length, these were restricted to 45hp in their home market and, depending on the model, it can be a real pain to release their full potential. Especially in the case of the MC28: that very cool PGM-IV ignition system uses swappable ignition maps stored on “smart cards” and, unless you can track down a nearly unobtainable HRC card with “race” maps, you’re kind of stuck. Supposedly, work-arounds do exist for this issue, but be sure to consult with an expert and proceed at your own risk…

It may be hard to see under that layer of dust, but this is a pretty nice bike, a few superficial scratches aside. The seller indicates that quite a bit of work has gone into it.

From the original eBay listing: 1996 Honda NSR250R MC28 for Sale

I won’t start by saying that is a GP replica and is a fast bike for a 250cc. If you are interested in the bike you know about it….

  • The bike has a complete engine rebuilt
  • all Honda parts
  • rebuilt complete crank (all the bearings)
  • all seals
  • all gaskets
  • clutch
  • tires
  • chain & sprockets
  • the rims are powder coated
  • all electrical working
  • PGM4 on the bike with one card

Fairings are OEM Honda not after market and they are in great shape no cracks at all

I have the bike for 3 years and I have done only 1500km on the engine. The bike is stored indoors all year and I start the bike every 5-6 weeks. I am just changing the fork seals this week (the one tube has a very small leak). The bike needs nothing just a rider to enjoy the ride. I have rebuilt the bike myself I have register and plate it here in Canada ON. The bike come complete from japan in boxes and I assembled it here. With the bike I have some parts that they come with it. 1 set of complete exhaust (you have the option Dog Fight or Ethos) The bike comes with stock.

1 set of front forks USD from a VFR400 NC35. You need to get the upper and lower fork clams and you install them on the bike. The bike comes with stock forks. As you see on some of the pics the forks and the exhaust I had them on the bike but the bike is complete stock now. The bike is located in Toronto Canada.

Bidding is up north of $6,000 with the Reserve Not Met, which is no surprise, considering what earlier NSRs go for these days. Even more so than usual, be sure you know what you’re doing before you buy this if you plan to register it for road use. It’s still a few years away from that magical 25-year mark, but maybe now’s the time to scoop one up for your collection, with an eye to registering it down the road.

  • The mc21 and mc28 engines are identical both have a 3d mapping system. The only difference is a minor porting change that doesn’t matter and a more restricted flywheel timing. The big difference is in the cdi box has some extra mapping to go with the key card system. So when you put in the key card for the race setting it unrestricts it but kills the lights and oil pump.

    Now you can do the wire splice mod and the rare p 030 race card mod to unrestrict it. But for some the ultimate mc28 is one with a mc21 flywheel since it has more advance on the flywheel pickups and ignition along with speedo setup. It is far easier to unrestrict this way.

    Technically speaking if you had a mc21 you can actually just bolt on swap the mc28 rear swingarm back end setup. Along with the mc28 bodywork rearsets and a set of mc28 pipes and aside from the ignition and triple clamps you’d have a mc28.
    Or in the case of this bike you can get a set of rvf 400 forks rvf triple clamps. Since the stock ones are cast steel.

    Grind off the bottom weld to remove the steering stem and swap the nsr stem onto the rvf clamps reweld into place. You can also just buy the billet aluminum triple clamps tyga sales for it I have done both.

    Not only do you get the inverted forks in the swap you get the bigger front brake rotors as well.

  • Don’t do the mc21 flywheel on an mc28 and the race cards combined. One or the other but both … explosion.
