What's the comparison from an NSR250 to an RZ350?

Please don't crucify me......I don't have my NSR home yet. I owned an RZ350 in the past and it was fun. How is the Honda going to compare to my old Kenny Roberts Replica?

Compare how?

I ride with quite a few RZ/RD's and swing a leg over them now and then.

All around. What's the acceleration/braking/weight/seating postition, etc etc feel like when you jump from one to another?

Handling is the first thing that hits you in the face when going from the NSR to the RZ. The Honda will walk on the Yami pretty easily. The guys I ride with have modified RZ's that make good power so on the straights maybe 40-70 mph it's pretty even. After that I'm gone. Braking no contest not even close. In the tight 1st gear stuff the RZ feels easier to throw around weight wise. Seating position the NSR is a sport bike the RZ is more of a standard type deal.

Absolutely legions apart really. The RZ harks back to the early 80's and is a fantastic bike in it's own right, but it will be blitzed by an NSR on any road with twists in it.

I owned an RD350 (UK version with steel frame) for a while and loved every minute of it, but in comparison it is like a club compared to a scalpel NSR.

The RZ has more power and midrange if tuned properly, but then it's 100cc bigger. The NSR has lightness and proper sized wheels!

The RD is a road bike, the NSR a race bike.

You want to tell that to the YPM boys, some hero on a 350lc did a 1'41.85" round Cadwell, that'd be good enough for top 5 in DP F400, top three in F250 easily.
It's also right up at the sharp end of the fast group, he'd be lapping those towards the rear for sure, now that would be funny to see.

The 350's have got so much grunt unless the 250 man is really on it the 350 will just be gone. Martin's NSRD thing leaps out of corners like a fast 400.

It's no faster than my MC21, but it certainly does grunt, and I had the be properly on guard not to get jumped by him out of some of the slower corners because of it.

If you are into that sort of thing, then he has the perfect answer -- 350YPVS motor in an MC21 chassis.

As for the guy lapping Cadwell fast on an old RD; that's irrellevant! Put him on something that actually stops and steers and then see just how much slower he makes you look. Talent is talent, and there are guys that can outpace muppets with 200hp on old 60's stuff if they choose. You want to try riding the same bike round the same track... laptimes mean nothing unless you are comparing apples to apples. You can't just compare everything and everyone by laptimes!

Yeah, when it comes to assessing bikes there's really important stuff like paint jobs and HRC trinkets to take into consideration Laughing

In a proper shootout I'd be pretty surprised if Martins 350 wasn't a bit quicker than your NSR though, Andy? The thing really is very quick indeed when you wind it up. I'm a bit of a 250 purist myself so it feels like cheating to me, but you can't argue with the performance of the damn thing.

I certainly take my hat off to the fella lapping Cadwell in 1.41 on the old rubber-framed LC though Shocked. That to me is very, very impressive. As a road-and-dyno junkie, if you could manage a sub 2 minute lap round there on your NSR, I'd doff me titfer to you too. That's as near as damn it 20 seconds slower than Elsie-boy! That's how impressive those numbers are Shocked. Come and give it a go on the 17th Aug. If it's anyting like last years do, It'll be stroker-heaven Very Happy. And a full day working out the magical ribbon that is Cadwell should be enough for you to get down to about 2 mins if it's dry I'd think. Personally, I'd just be happy if I could get over the mountain without coughing up a little bum-peanut every time Laughing

Is the track you guys are talking about tight with no long straights. I noticed that even though these RZ's are putting out more hp than I am when we hit higher speeds the fairings on the NSR is a huge help.

When it comes to the corners or braking I don't see anything that can be done to the Yami's to make them match a NSR.

I will give the nod to the RZ/RD when it comes to exhaust note though.

On paper, maybe, but in the real world it's not the case. We did the Okehampton to Torrington road (favoured ride-out route part one) and while there's no denying it is quick, it's not really got anything over mine as long as I concentrated!

The real benefits were obvious though... Martin's bodyweight and 100cc's of extra bottom-end! There were a couple of slow corners where he would pull a gap, and I had to be in just the right gear at the right RPM or he would've got away. I had to really work the motor a few times, whereas I could see he could ride it almost 4-stroke-like at times and still be bloody fast. He needs to put on 20kg! Laughing

His 350 would probably flatten any relatively "normal" modern 250.

It was a while ago, but I recall I certainly wasn't giving it the full berries on the ride up to torrington (or back).....but then that's a reflection of my own tendancies rather than the bike, but it does show up as Andy says, the 'flexibility' the extra 100cc gives.

It has to be said though, that a stock RD/RZ is light years behind an NSR....(and my motor is far from stock so not really a useful comparison), Craig, you'll love the NSR Wink



Andy...you've still not ridden mine yet, do you fancy a little go on it sometime? I'd really value your comments as an NSR expert (suspension might be a little soft for you though Laughing )

A bit of onboard from last years 2stroke (mainly) thing at Cadwell for you below. Part of it is fast and flowing and part of it is is quite nadgery - with an excellent wheelie take off point too. Great circuit Very Happy

Guest appearance from Fontyyy in this clip too I think?:

Hi Guys
I had a rz250 with 350 crank +barrels a few years back . It could just keep up with my mates Kr1 to 130kmph but it didn`t handle well at all. I think my nsr is way faster than it was.

I just got home with the NSR. Was about 1420 miles round trip from PA to GA and back. The owner gave me directions for my test ride which included some nice long straights and some curvy roads, all with little to no traffic.

My original question? Forget it.
