My money is on the 360-degree crank Honda V4s as in the RC30/NC30 bikes: https://youtu.be/uTxe1_MPdiw

I love my 1991 VFR400. The Tyga exhaust takes it to a whole new level. Worth every penny. The extra 3500 RPM on top of the RC30 are nice too. Plus an NC30 can be had for about 1/5 the price of an RC30.

https://youtu.be/f-1HwvLLNEI Does a good job capturing the exhaust along with the straight-cut gears in the valvetrain and the intake noise.

The VFR had such a great unique sound, could hear them approaching in the city. I had a 1998 which didn’t last too long but it was fabulous sounding. Only four cylinder bike I owned, it’s been twins all the way for me otherwise and for my ears, nothing beats the V-twin grin :) But older VFRs before they got heavy are wonderful.

On the subject of the article, I hooned an F355 around Silverstone and while it sounded good, it was dull to drive at lower speeds and the Elise spanked it for fun.

The VFR400 ran for three generations (NC21, NC24, NC30) from 1986 to 1992. The successor was the RVF400 (NC35) which had a similar (same? different cams?) engine to the NC30 but a different intake and tank and inverted forks. It only ran as late as 1996. There were complimentary VFR750s for some of those years, including as late as 1998. Was your VFR a 400 or 750? If it was a 750 you had one highly desirable bike. From what I understand the last Soichiro himself developed.

Regarding the heavy weight in the later 1990s the VFR name was applied to sport touring bikes that had V4s but not big-bang 360 cranks. My NC30 weighs less than 400lb wet and is definitely not a touring bike.

Agreed on the V-twins. I would still love to have a RVT1000 but those command too high a price when Ducati Superbikes can be had for half the price.

I had an 800 and it was slow and heavy to my mind, was not devastated when it was stolen.

We didn’t see too many 400s in the UK, I think they were all unofficial imports but was a long time ago to remember.

Mate has a VTR1000 Firestorm if that’s what you meant? Outstanding bike, extremely hard to keep under 100mph, fuel tank was genuinely stupidly small. The SP1 and 2 were the superbikes IIRC and different beasts to the Firestorm, never had the pleasure of riding one of the superbikes. But yes, a Duke 998 over an SP1 I think.

The RC51 was the successor to the RVF750R (RC45) which was the successor to the VFR750R (RC30) and was built to beat Ducati at their own game in the superbike world championship. In the US the RC51 was called the RVT1000R, in the UK and Australia it was called the VTR1000 SP1 or SP2. The VTR1000 Firestorm (SuperHawk in the US) is a different bike, not intended for racing homologation but designed for the street. The VFR800 was a sport touring bike, very different from the RC30. The NC30 and NC35 VFR400s were sold legitimately in the UK after several years of grey import but were unreasonably expensive. My 1991 VFR400 was originally sold in Japan (1991 was JP-only), was imported to the UK (grey) and made it to the US as soon as it was 25.

These bikes were the end of an era. After the RC51 Honda went to the inline-four CBR1000RR Fireblade and never looked back.

I have exactly the same bike as well! :)

Cool! I have had trouble finding Bridgestone Battlax tires for it. I still have a decent pair on the bike but they won't last much longer. There are some tires available domestically that are close but nothing is quite right. I have had great luck getting parts from Rick Oliver and occasionally Aliexpress.

They are from a sweet spot in history. There was adequate technology to make them reliable and high performance but inadequate technology to truly perfect suspension geometry and engine layout. The big-bang four was intended to reduce rear wheel slip by maximizing dwell time between impulses. Modern bikes can make far more power and let computers do the traction control. But the VFR400 is a carbureted fully mechanical bike. The ignition is electronic but no more complex than points. Just more reliable. It's a real joy to own, maintain, and ride. It isn't even fast, but it sure feels like it's doing something!

Where are you located? Here in the US they're incredibly rare and except parts that were used on other bikes that were actually sold in the US, you pretty much have to order from the UK. I had to order my BT-090's from thevisorshop.com and ship from the UK. Stupidly expensive...

My NC30 is actually an EFI conversion project running Megasquirt. I got tired of trying to get to the carbs... ;-)

I’m in Seattle. The shop I bought it from had two. They specialize in importing “classic” foreign vehicles that were never sold here. Mostly kei cars from Japan.

When I did the valve adjustment I asked for parts for some other Honda that was sold in the US. There’s only two diameters of shim so once you find a compatible model you just order parts for that. Same for oil filters and non-exotic parts. Other than that you’re calling Rick.

My carbs work perfectly and I refuse to ask or answer any further questions on the topic ;)

Thanks for the tip on thevisorshop.com.

I'm intrigued by the EFI conversion. That seems like a big project. If you want to chat more send an email to my username at the domain in my profile.
