If RCs are so slow,

How was it so successful? Racing versions that much better? Nicky’s talent? What made the RC such a good racer, and did the style of track help?

The Factory HRC RC51 Superbike does not share one single bolt with the production version. Literally not one. Everything on the Superbike was different. Different frames, engine cases, heads you name it all the way down to the bolts that hold on the bar ends are different. The only thing they really have in common are the bore & stroke numbers of the engine.

The bike was successful because it had millions of dollars thrown at it to win at all costs and with that came a commensurate level horsepower and handling. Every Pro rider that rode an RC51 Superbike had excellent results on it. You didn't even have to be that good of a rider to win on the RC51 Zemke, Edwards, Hayden, even Kurtis Roberts won races on it and while they are all Pro Racers I would not consider any of them to be top level racers like the aliens of MotoGP. Don't forget that they were also racing against 750cc Inlines as well...

Why are rear swing arm, throttle bodies and frame described by some as “race spec?”

Because it sounds cool and people are easily duped into buying things when they think they are somehow special.

True, but Ducati's built on 10 year old technology. The RC51 beat them at their own game. The downside to all that V-TWIN horsepower was they were swapping out motors every 250 or so miles or the crankshafts would shoot craps

highly strung yes, crankcases were the weakness i think, but not slow when they were in one piece, even Pier francesco Chili's "privateer" bike would regularly top the speed charts

They didn’t share anything with the factory SPW’s but many privateer complete racer package SP’s did very well in competition around the world. Nearly all had different cranks, strengthened cases, rods, pistons and cams plus modified gearboxes. This on top of significant suspension upgrades.
Any bike with that much development and spend can be competitive. HRC helped out with fitting the SP1 race kit based items for the SP2 For homologation rules. Swingarm, forks, headstock, TB’s etc.

LDH nailed it, no correlation to our street machines at all beyond the moniker. And even still, our SP's aren't what I'd call a slug...even with me on the seat.

Duct tape can't fix stupid...but it sure helps muffle the sound
