You really have to think about,the age of the RC-51. Stock RCs were 135hp at rear wheel. Which when Honda released the bike(12 years ago) was pretty good.
But technology hasn't stopped... 1 liter bike puts about 50hp more (170-185 hp), and suspension has improved..
AS stated above- You can buy an improved, more powerful 1 liter bike now.. Just doesn't mean that it is needed or can be used on the street..

Sure... 55.661411,13.361167 - Google Maps
You do know the SP2 has 136 bhp at the crank as stock? So getting around 140 to the wheel isn't even a great challenge?

Unless you were able to mount the engine directly to the swingarm
. Then you could bolt the wheel directly to the crankshaft and have a true 136hp at the wheel.

Well, I know darned well the difference between the numbers at the crank and the wheel...
The thing is, if you bolt a rotary supercharger to an SP2 engine, lower the compression slightly (shim), and set up the fueling, then 170 at the wheel isn't even a challenge, 140 is long gone and dusted... It's actually "downgeared" for the SC run-in at the moment, and it should be at around 180 at the wheel once that's done, or more depending on bravery/stupidity...
And no, it's not mine... But I'm still trying to convince myself that I don't really need to do that to my bike, after the testride I had... Fifth gear powerwheelies anyone? No clutch, just throttle! (And not a whole lot of throttle even!)
And actually, most stock SP2's put out a good bit more than 118 at the wheel... The least I have seen was around 122-123... There is a significant difference between the SP1 and the SP2...

are you logging/documenting the build? I would love a play by play with photos!
PS I was assuming that you were talking about NA when you first said 180hp.... unless you went with the Kainzinger package.

The RC51 was a homolgation special so that Honda could race a 1000cc twin against the Ducatis. Like the Kawi ZX7rr, it got a rep from the street riders for being a little heavy in it's class because it took a good stripping and some HRC kits to come down to race weight and up to race power. Whatever hp world superbikes made (170-180?) in the years the RC51 was raced represent it's potential if you've got the cash to get there.

there have been some that have probably reduced the weight even lower, improved the handling even more and got more power out of it then the HRC factory ever did....

My bike (SP2, not my VTR) is at the moment not running, and in need of an engine overhaul... As well as being stripped of anything that I deem unneccesary since it will most likely be track only... It won't be prettied up, it will look like crap... But it will move... And NO! I'm not doing an SC... I haven't got the funds... It's possible I get antsy in the future and reverse that decision but for now no SC...

However, I couldn't care less about the numbers at the crank... I measure where the rubber meets the road... And while my tools aren't nearly as sof'stcated as the manufacturers, they show real numbers... All the way from 1 to 9... Eh wait... 10... I got ten fingers, so that's the one...

Yeah, I have yet to find a manufacturer that quotes the numbers at the wheel in their material... It's just not as impressive...
