Two-Stroke Resto-Mod: 1984 Yamaha RZ350 Kenny Roberts Replica

1984 Yamaha RZ350 L Side Front

While many motorcycle fans are sticklers for originality, I take a more flexible view: basically, if you make changes, even significant ones to the bike, but manage to maintain the spirit of the original, I’m probably on board. And while this Yamaha RZ350 isn’t quite stock, the seller obviously wanted to stay close to the look and feel of the original, with suspension improvements that should make the bike even more fun to ride.

If you live in the US and want a sports two-stroke of recent vintage, you’re likely looking at some tired ex-Japanese market bike imported through Canada and now of very questionable provenance. Or you’re looking at an Aprilia RS250.

1984 Yamaha RZ350 Dash

Two-stroke fans here have found slim pickings in the last 20 years or so, but it wasn’t always that way. Back in the 1980’s, that glorious era of neon, Nagel prints, big hair, and slightly ridiculous motorcycle acronyms, two-strokes were still popular, and enough people cherished their RZ350’s that they’re some of the most accessible sports two-strokes available here in the US. Sure, there are some thrashed bikes out there, but it’s not too hard to find well-preserved examples if you look.

1984 Yamaha RZ350 Fairing

Which is especially surprising, considering they were produced only between 1984 and 1985. The bikini-faired sportbike was powered by a 347cc two-stroke parallel twin that was evolved from the RD350, but added liquid cooling to the package, along with Yamaha’s YPVS which, as you can probably guess, stood for “Yamaha Power Valve System.”

At the time, the RZ350 was a serious back road tool and was one of the best-handling bikes available at any price, and required rider involvement to maximize the two-stroke powerband.

From the original eBay listing: 1984 Yamaha RZ350 for Sale

Great bike that needs nothing, I’m selling to fund my Aprilia RS250 project. Specs below:

Motor:

200 miles on fresh top end and crank rebuild. Crank was trued and welded, Wiseco pistons on 2nd oversize bore. OEM head gasket. Zeeltronic CDI (non- programmable). Genuine Keihin PWK 28 flat slide carbs, uni pod filters and quick turn throttle with custom cable and aftermarket kill switch. Banshee adjustable ignition timing plate (currently running +3 degrees from stock). Allspeed expansion chambers that were repacked and powder coated black (sound great, not too loud). Oversized aluminum radiator. The carbs are jetted properly (if not a little rich) and the bike runs great. Starts on the 2nd kick cold, idles nice, pulls hard and is extremely smooth. Setup for 40:1 premix and premium pump gas.

Chassis:

Aluminum FZ600 swingarm (professionally machined to fit in the RZ frame). Fox shock with ride height adjustment.   FZR wheels (new bearings, powder coated black). The sprocket carrier was machined for proper chain alignment with the wider rear tire. FZR forks (fresh rebuild),triple trees and clip-ons, tapered head bearings. FZR brakes front and rear, stainless rear line. New chain and sprockets, chain is a gold o-ring 520. New tires. The bike handles and stops very well.

Body:

All of the paint was redone with reproduction decals and professional clear coat. Reproduction solo cowl with bump pad. Inside of gas tank is rust free, it was professionally coated by a radiator shop. Manual style petcock. OEM seat with no rips or tears. Custom laser cut stainless bracket to mount the OEM fairing and gauges to the FZR triple clamps (looks factory). The frame has original paint and has a few minor scratches and nicks but overall is very presentable. I left off the horns and turn signals for a clean look but the wiring is still there if you want to add them. The rear fender was also eliminated and tail light tucked up a little higher.   Included are the stock rear fender and tail light bracket.

Full disclosure: The motor numbers and frame numbers do not match. The original engine cases had damage to one of the crank bearing journals and it was decided to use a different set of cases. Clean title in hand which matches the numbers on the frame. The damaged cases with matching numbers will be included. The odometer shows 2400 miles but I have no idea if that mileage is accurate or if they are even the original gauges. It doesn’t really matter since everything on the bike from the ground up is essentially new or rebuilt.

Bidding is up to $3,999, but there’s plenty of time left on the auction. The seller has obviously put plenty of work into it, but will purists balk at the changes?

Buzzy Little Bee: 1985 Yamaha RZ350 for Sale

1985 Yamaha RZ350 R Front

Yamaha made a name for itself in the US building giant-killing two-stroke parallel twins that powered the RD and later RZ models like this 1985 RZ350. The 347cc engine reatured liquid-cooling and made over 40hp stock, with plenty more available with careful tuning. While Honda largely focused on their heavy, but very sophisticated two and four-cylinder CB motorcycles, Yamaha’s whippy little two-strokes terrorized backroads and race tracks all over American and Europe, creating a cult following that persists to this day.

1985 Yamaha RZ350 L Side

Two-strokes have never lacked top-end power, but their light-switch power delivery left something to be desired for street riders and, in th 1980’s Acronym Wars, the “power valve” was born. Yamaha’s version was, of course, known as the YPVS that used a computer to adjust the exhaust ports. The “Yamaha Power Valve System” plumped up the midrange of the raspy little two-stroke, meaning you could have your cake and eat it, too. Assuming you didn’t mind a little blue smoke in your eyes…

From the original eBay listing: 1985 Yamaha RZ350 for Sale

The 1985 Kenny Roberts Edition RZ350LC offered here is one of the quite rare leftover models with revised graphics that somewhat resembled the 1983 UK versions, but with gold rims and the Kenny Roberts signature, originally sold as an RZ350NC2 in California only from late 1985-6. It has been owned from new by only two enthusiasts and has been very tastefully modified with an original 1985 full fairing and Corbin Gunfighter single seat. Mechanically, the hugely desirable Pro-Design Cool Head was installed for increased cooling, and a Toomey exhaust.

The bike runs exceptionally well. It starts easily, idles well and has great power delivery. It shifts through all gears perfectly with a good clutch. Suspension feels taut and the brakes work very well, front and rear. Cosmetically the bike is in good condition with the usual scuffs of a bike with 17,000 miles, that is 32 years old.

The bike comes with a clean, clear California title and a substantial box of spare parts, including stock fairing, original exhaust pipes, turn signals, etc.

These are not bikes for the inexperienced or faint-hearted, with huge wheelie-popping performance on tap when the revs rise.

1985 Yamaha RZ350 Pipe

This particular RZ350 features a very stylish full-fairing that I’ve seen on several bikes for sale recently. I’m not sure if it was a factory option or not but, painted to match, makes for a very nice machine with light weight and bike-bike style. Parts availability to keep an RZ running should be no problem, but the included spare parts is just icing on the cake.

1985 Yamaha RZ350 Engine

 

A price of $6,900 means you’re looking at the higher-end in terms of pricing for these, but it looks like you’re getting a well cared-for, thoughtfully-improved, and very practical classic for your money.

Tastefully Upgraded 1987 Yamaha RD350 YPVS NII

Update 3.1.2014: The seller has decided to pull the bike from the market and ride another season. -dc

Normally when you see one of these on our site it’s available in Europe. Not this one, it’s in Texas and available today as our latest Featured Listing! Legally imported with paperwork in 2011, this one should transfer to most states without a hitch as a classic. As you’ll see in these great photographs (which are available in high resolution in the gallery below), this one has been nicely upgraded with period correct pieces that blend right in and that exhaust finishes it off nicely.

Choose 1 out of 4: Yamaha RD 350 (Germany)

It seems as the RD350s are having a second life among enthusiats all aorund the world. The seller of this excellent sample found in Germany, actually has four of them. He mentions that highest bidder will get to choose which model he brings home from the 4.

$T2eC16d,!zEE9s3!Y8u0BRkT(PLw2!~~60_57

The one pictured here would do for me.It is in beautiful conditions and with a BIN set at 2500 EUR, this is a no brainer, honestly! I mean, what are you waiting for. This is one of the most versatile and exciting 2 strokes ever made. It looks cool too. And that sound…mmmhh.

$(KGrHqJ,!qgFF5GsZP-BBRkTYlYqhw~~60_57

Spares are easy to find, it is a 2 stroke but it is not a race 2 strokes. You can comfortably cruise around and when you want to go a bit faster, just keep the needle on the right side pinned anywhere between 7000 and 8000 rpm. That is the sweet spot for an original 31k model. This bike won’t scare you for power, but the super light weight combined with those wishy-washy stock suspension, will make the ride an exciting experience.

$T2eC16R,!zoE9s5ne3BuBRkT,BNurg~~60_57

I love it. It’s loud enough with the stock catalytic mufflers, fast enough, comfortable enough, rare enough, good looking enough, cheap enough, reliable enough (as long as you keep it stock), it is…everything enough ! it won’t even take much space in your garage, so don’t use that excuse.

$(KGrHqZ,!lQFF845QzJSBRkTbPmlv!~~60_57

This bike had recently new  increased volume cylinders and new pistons fitted. The handlebar doesn’t look original like a few other small bits, but what the heck, this bike is made to be ridden more than looked at.

And here’s a video of this actual bike, for you to appreciated the sharp sound indicating a healthy engine condition:

“R” You a “RD” Fan ? 125, 250 And 350 (Switzerland)

If one RD isn’t enough for you, or if you want to start a series collection, here is an opportunity to acquire some (125, 250 and 350) of the 1 and two cylinders all at once. In addition to these also an 80 cc version was available at the time with a bit of search or constant reading of RSBFS it won’t be too difficult to find one. The seller is giving away the 250 (pictured below) and the 350 together at a price of about 3200 EUR. In addition he will give you a few spares which are always a plus !

31L84red

Coupling these in the same ad, makes sense as the two share most of the components apart from the combustion chambers. The 250 is in good original conditions,  while the bigger brother is mentioned to be good for spare parts or would require some level of restoration. The smaller twin powered YPVS, has 35000 km and was first registered in 1988. The 250cc is somewhat more rare.

big_yamaha_rd_img_0166

As a separate ad, the seller is also putting on the market the black 125cc which you saw above in the background:

big_yamaha_rd_img_0163

All of the above are part of the LC series, that means they are all Liquid Cooled, as opposed to the previous generation RDs. Liquid cooling improves the efficiency of the engine by stabilizing the temperature at values optimal for the combustion. It also reduces the mechanical noise due to piston lag, reduces the size required for the parallel cylinders (in case of the 250 and 350 cc) but introduces a higher level of complexity given by the presence of a radiator and the required ancillaries to make the water circulate back and forth.
If interested in building up an RD garage or snapping this 250cc model, go ahead by clicking on the links below:

Need 100cc More? Get an RD 350 (in Germany)

This past week we posted a few rare 250cc 2 strokes, covering brands like Kawasaki, Honda and Yamaha. If your motorbike riding style is less track oriented, you might prefer to have a few more horses under the seat and a less sport focused searing position. You want a naked RD 350! With 60 Hp and an overall light package (you don’t even have a fairing on this one),  the power is enough to pull a wheelie here and there and have a great fun experience.

$(KGrHqJ,!mIFGHm-d1F2BRk6!rBTbQ~~60_57

After all,  this is a strong all rounder smoker. Some say, that the smile factor of riding the 350 is even higher than the one on its bigger brother, the RD 500cc. That would be because the 350cc having cylinders with 175cc instead if 125cc, produces higher pressure, and therefore higher torque, at lower rpm. Also the sweet spot of the engine is broader as the twin is way less complex than the V4. Add the lack of bum heating tail exhaust pipes, and there we go…I also like the naked looks of the RD better the the faired versions. Lacking a refined “Deltabox” type of frame, it is both better to look at and more of street oriented tool.

$T2eC16d,!zUE9s38+qI3BRk6!of78g~~60_57

The sample found in Germany (again…sorry for the US readers) was originally part of collection. Later it was purchased by the current owner who, due to lack of time, is now willing to part from it. The bike is a 1986 model year but was first registered in 1989. With 28.000 km on the clock, it is also 100% stock, including the turn lights and mirrors. While there are plenty of RDs around, sure there aren’t many like this.

$(KGrHqV,!qMFGBdUgLn9BRk6!MuTYQ~~60_57

How much does it cost ?

With just above 1000 European bucks, you can start to play. With 3 times that, it will be yours, now!

That is good value to me, what do you think ?

Carbs will need new floats… I foolishly left the fuel petcock on when I went on a short vacation. The VP MR race fuel gummed up the carb bowls and floats. I have cleaned the throttle bodies extensively but will most likely have to replace the floats.

A very cool custom bike that appears to be at a very good price for the right person.  See the Craigslist ad here.

1985 Yamaha RZ350 Kenny Roberts

Located in Los Angeles, California is the rare color 1985 Yamaha RZ350, Kenny Roberts edition.  This bike has been well maintained and completely gone through.  This example claims to be completely stock except for the smoked windscreen, tires, and battery.  It sounds as if the majority of the rubber parts on this bike have been replaced only because of their age–which is a good thing.  The bodywork is completely original.  The seller states that the only defect is a small one on the tank decals.  This bike is California titled and registered.  Priced at $5,499, this bike is located at a dealer but not inflated in price just because of that fact.  See the Craigslist ad here.
