Anyone see the feature in the new Performance Bikes, (great mag, Guy Martin as a regular contributor!) on the SP-2 (RC51)? The mods the dude has aren't anything outrageous, but the comments of the tester after riding a "proper twin" were great. Check it out.

Semper Fi! :rockon

Performance bikes is always a good read, probably best of the British mags.

They're the two bikes I own, in the future(sometime) I do plan on adding an SP2 to the stable, I wouldn't bother with an SP1 as I think the refinements to the SP2 make it a better bike than the SP1.

I know mate, I just always have to defend the SP's name. :D You will love your RC51 when you get it, but its going to take you a lot of time and money to get it to the level your 30/45 are at.

I am in the process of building my SP2 into an HRC spec kit bike with a few factory parts per my HRC Kit service manual and I expect the results package to be better than any of the previous rounds of modifications I have done.

I saw the article as well. I was impressed. I also liked that the guy also has an SP-1 for the track that was also well sorted.

factually you are wrong.

negligible mods were made and for a road bike you can't hardly tell any of them. The 2002 swingarm is nicer but few can actually say on the road they make use of it and they can be swapped. the TB are a we bit bigger and they gain a HP or two up top at the expense of losing them down low and other then that there is nothing IMO worth noting between the two

I see the classy wonder from downunder speaks again . As a gift to the sump pump maestro , let's all hold hands and forget just for a moment that both versions of the RC51 will hand those V4 powerhouses their asses on the street or track .

SP1 v. SP2
From Motorcyclist:
2002 Honda RC51 VTR 1000 - Road Test & Review - Motorcyclist Online
2002 Honda RC51 VTR1000 Motorcycle Review

Race-shop revisions make the RC51 a much-improved streetbike for 2002
From the February, 2009 issue of Motorcyclist

Whatever the multimillion-dollar factory riders want, it seems they get. And if any of those changes happen to benefit street riders, well fine--but it's almost an accident. So it is for 2002: A multitude of tweaks have arrived to make the '02 RC51 more competitive on the track, but the trickle-down effect is that the bike is now much improved for puck-wearing plebes.

For '02, Honda chose to tweak the engine a bit, put the entire bike on a part-by-part diet and significantly revise the suspension, chassis and swingarm. Down in the engine room, the throttle bodies have been supersized from 54mm to 62mm, and the two injectors feeding each combustion chamber now sport 12 laser-drilled jets, rather than the four little garden hoses of the previous bike, for a finer spray. The injection and ignition mapping were tweaked, also, resulting in throttle response that's as smooth and creamy as a nougat filling. (Don't tell Nicky; he's got a sweet tooth.) The new motor feels same-same in terms of power output; Honda claims a two-horsepower increase for 128 hp at the crank--but the low-rev snatchiness is nowhere to be found.

The engine is warmed over, but as Honda's Doug Toland said at the intro, "All of the 'magic' of this bike is in the chassis." The new Pro Frame looks similar to last year's and has the same amount of rigidity, but weighs 260 grams less and is more linear in its absorption of stress thanks in part to the new stamped engine hangers (previous units were cast). Also new is a steering-damper boss up by the steering head, but on the stock geometry you'd be hard pressed to make this bike shake its head on the street or track.

Even though the steering-head angle has been reduced one degree to 23.5 degrees--the steepest of any Honda--the RC51 feels planted at all speeds, even at 130 mph through Willow Springs' infamous Turn Eight. There you sit, tucked behind the splendid new windscreen that's 1.2 inches taller than last year's, sensing no instability from either end of the bike. Of course, the new swingarm (890 grams lighter) is 16mm longer and aids the stabilization effort.

Right above that sexy new swingarm is a revised shock (115 grams lighter). It's been repositioned to allow room for aftermarket exhaust systems, but also had its linkage ratio tweaked (4 percent softer on the bottom, 5 percent softer on top), even though spring rates are the same. Nine percent more compression damping has been added along with 11 percent more rebound. Up front similar tweaks have been applied. The fork (145 grams lighter) is now 9 percent softer on compression, up 16 percent on rebound, with the same spring rate. Fork travel has also been increased from 4.7 to 5.1 inches. These changes make the bike feel plush and controllable--a far cry from the wooden feel of the previous bike. The suspension is simply awesome now, soaking up midcorner ripples yet never getting out of line or doing anything untoward.

Steering effort is drastically reduced on the new bike. The RC51 is no 954 in terms of flickability, but the new bike turns in with an ease and precision that's head and shoulders above the old bike. Pick your line, shove the bar and you're there. The previous unit's brakes were fine, but the new four-piston jobbies are even better. The old brakes were extremely progressive--once activated you only had to move your finger a smidge to stop the bike. The new brakes are totally linear and require more lever travel, providing better feel, easier modulation and more feedback.

Speaking of feedback, the RC51 comes wrapped in a new flavor of Dunlop rubber named D208. The 208s are quite soft for a street tire, which allows them to heat up quickly and throw down GP-like grip.

Feedback from both the front and rear was excellent, with excellent straight-line stability and precise steering at high and low speeds.

Our only complaint (and we think some folks at American Honda's marketing department will back us up on this) is that the bike looks exactly the same as last year's. Europe gets a bitchin' white/grey, but we get the same paint job as before. If you go out and buy the "new" model with all the killer updates, you want people to know, but it's literally impossible to tell the two bikes apart from a distance.

Paint job aside, the changes made to the RC51 for '02 signify a Paul Bunyan-size step forward. Oh, did we mention the '02 RC51 is the same price as last year?

alot of fluff in that article:rolleyes:

two HP and revised parts that everybody who bought one got rid of

the revised forks and shock are still the first items to go on any 51 and the steering of the sp2 is not noticable on a street ride. the fueling low down is not cured with a SP2 and that article is a sales pitch more then anything

"and the two injectors feeding each combustion chamber now sport 12 laser-drilled jets, rather than the four little garden hoses of the previous bike, for a finer spray. The injection and ignition mapping were tweaked, also, resulting in throttle response that's as smooth and creamy as a nougat filling."

look at this crap:cool: garden hose? creamy as a noughat filling? come on now that is a stretch

you most likely are reworking your forks and getting a shock and a PC and exhaust so really all is for naught

buy a SP2 swingarm and a dan dyle or mro, or jon or ben sus link too and be done with it:)

Why are you so negative all the time?

http://www.speedzilla.com/forums/street-track/64137-sp2-performance-bikes.html#post649622

i posted honestly and i am sorry you took it as negatively

will try harder to over look the facts and agree with what is not truu:D

on the article IMO it is a fluffly sales pitch to sell 2002 bikes vs the older 2001. i have been a owner for over 10 years and i know what is, and is not. it is hard as a owner and forum member for alsmost a decade with 541 owners to look at writiers drivel like that as a real fact, again sorry for calling it as i see it.

buy the PS it is a much better bike then the SP1

I don't want to get into an arguement, as this is just my 2 cents, yes that article may have been a bit of a sales pitch aimed towards the 2002 model, but 'factually' he is right, the SP2 IS slightly more refined than the SP1, which is exactly what aus_rc45 was saying. On the roads you wouldn't really notice any difference at all. Some parts may even get replaced with aftermarket parts as well to make all those changes null and void (except maybe the stiffening of the head stock), but in the end, who really cares. If he wants to get an SP2 over an SP1 for what ever reason, then that's his decision. For example and price aside, I'd much rather an RSV4 Factory than an RSV4R. They are much the same and on the road in real world conditions, you probably wouldn't even notice the difference between them. I know I could always buy all the parts to make an RSV4R like a Factory, but why would you bother when you could just buy the Factory? I'm sure aus_rc45 is buying one just for the collectability, not for the performance or handling ability. Which then would make sense to buy a 2005 model so that it is also a little bit newer to boot.

Opposite that. He would then want a 2000 model.

I finally let my PB subscription lapse after sixteen mostly great years. I first started purchasing them over the counter at the Little Professor Book Store, in Brainerd, Minnesota in 1993. The magazine morphed numerous times in that span. It's still a good read but a far cry from the entertainment value produced in the nineties.

Yeah, fair call. You're probably right.

Personally I'd get a 2000 AND a 2002 as they won the championship in those years.

Finances permitting I'd like to collect a 1988 or 89 RC30 and a 1997 RC45 to go with my SP2 :)
