Yamaha’s Legendary TZ: 1975 Yamaha TZ750

Yamaha's Legendary TZ:  1975 Yamaha TZ750

I think you can argue the TZ750 is one of Yamaha's most iconic race bikes.  It takes you back in time to when bikes could truly be nasty beasts.  I think it is also a time when tire and chassis technology hadn't quite caught up with engine performance.   I've posted this info before but it is worth a second look if you haven't seen it before.  It is from a little comparison on

the 1974 TZ700 and the 2000 R7 Superbike

TZ700 R7
Wheelbase 56.28" 56" 
Weight 345 lbs 356 lbs 
Front Tire  3.25 x 18 3.5 x 17
Rear Tire 3.5 x 18 6 x 17
Horsepower 145 173

How about the rear tire size!

Here is the auction info:

Here we have for sale a very rare 1975 Yamaha TZ 750 GP road race bike. This bike is in fantastic running condition. Yes, this TZ runs like you would not believe!! The 4 cylinder 750cc two stroke engine is all rebuilt and had virtually no time on it after a proper break in. The transmission and the chassis were rebuilt too but never raced after the rebuild. The bike runs perfectly down the street. The fairings are 1976 TZ 750 and same with the exhaust pipes. The bike also has the rare magnesium racing wheels on it. I have the new never mounted spoke wheels too. The bike is painted pearl white with red. The gauges are all in perfect working order. The rear shocks were cantilevered to improve the rear shock feel and performance. The bike has all original parts on it. This bike won mutiple races at Daytona back in its hay day. I have all of the documentation with this bike with all of its racing provenance. I have boxes of original TZ 750 parts. Two gas tanks, wheels, wind screens, etc. This is the definition of a vintage collectors race bike!  Its the best sounding 4 cylinder two stroke race bike you will ever hear.  Its a beautiful race bike with a ton of history and do not let this one get away! You wont find a more unique, rideable race bike.

She is looking good under the hood.  You basically have a restored bike that hasn't been used since.  How rare are the wheels the seller describes?  Here is some good tech talk on the TZ750 I purloined from an interesting blog on Yamaha race bikes:

To start off from the beginning, what Yamaha actually did was graft two 350 cc twin race engines and together they belted out 90 bhp from the crank with bore/stroke ratio was 64mm x 54mm. These twins were the TZ350. The crankcase itself was of ultra-lightweight magnesium construction, with the crankshaft having blanked off ends to keep the engine as narrow as possible. The primary drive was taken from straight cut gear cogs from the middle of the twin crankshafts. A massive dry clutch sat along with three of the exhaust pipes on the right of the engine. A spindly, tubular steel frame held the engine, with narrow telescopic forks at the front and conventional twin shocks at the rear. Later, TZ750 models (also known as OW31s) had vastly improved monoshock rear suspension, with a cantilevered swingarm to improve handling. It was named F750 as a prototype although it was actuallt 700cc. Awesome! 90 bhp from a 2 stroker would shred any kind of race tire way back then. Kel Carruthers, the 1969 250 world champ was the first man who tested the bike. He removed the initial glitches by increasing the swingarm and improving the suspension. Still except for Kenny, the others were quite slow on the tracks as they were not able to handle it as the bike had small fork tube and chassis. After about 3-4 races, Yamaha added some more power! Another 20 bhp. Why? Because according to Kel, "It wasn't as fast as it could have been. They were really conservative in the way they built it.” In a way, Kel was actually serious. You know Yamaha back in the late 60s had V4 250cc GP bikes which were making around 75bhp, so logically the bike should have around 140bhp. Of course there was no chasis or tyre which would have hold it was another thing, but come to think about it, the bike with modifications later did belt was that much power.


I honestly can't imagine the hit this bike would have.  I've always thought a healthy 250cc two stroke gives a nice adrenaline rush.  Maybe it is an optical illusion but I don't know how that upper muffler doesn't cook your leg.

It will make an excellent addition to any collection or instantly turn you into the bad boy at  the track.  If you interest still isn't peaked it looks like it is a "no reserve" auction.  It is going home with someone.  Click to win.

Classic Italian Stunner: 1981 LAVERDA JOTA

For Sale: 1981 LAVERDA JOTA

When it comes to the pages of RSBFS, Laverdas are relatively scarce. Sure, you might find the occasional RGS Executive, but most of what we have posted are the more modern incarnations of Laverda, such as this 750S or this 750S Formula. But today we have the legendary Laverda - the 1000cc JOTA.

The Jota was the brainchild of U.K. Laverda distributors Slater Brothers. Convincing the factory that they knew what Laverda needed to produce, the brothers created the specification. As the Slater brothers had a history of offering modified Laverdas - especially those based on the new 1000cc three cylinder "3C" platform, what rolled out of the Laverda factory in 1976 was essentially a factory version of a Slater build. Add in a cool name - Jota is a native Spanish dance in triple time - and history was made. The model ran through 1982 before being discontinued and morphed into the RGS line.

From the seller:

This bike appears to be in excellent condition for its age. There is nothing quite like the cadence of an inline triple - either at idle or at full song. This bike, this legendary model, looks pretty deserving of a good home.

The auction for this bike is going on now. Interest has been pretty consistent since auction opening, and the current bid sits at $8,450 with reserve still in place. I have no idea where this one is going to end up, but it sure will be fun to watch. For more information and details, click the link and jump over to the auction. Good Luck!

Executive Express: 1983 Laverda RGS Executive

For Sale: 1983 Laverda RGS Executive

Quick - name a famous manufacturer of large displacement, 3-cylinder sportbikes. No, not the UK one. Think Italian. Benelli is a close guess, but not really known for bigger bore machinery in the US. Reach a little deeper into the history of Italian motorcycle manufacturing to pull out today's find: Laverda.

Founded in 1949 (although the name was associated with farm equipment engines since 1873), Moto Laverda S.A.S. started out as most motorcycle firms in post-war Europe: building econimical, small displacement bikes for transportation. Bikes grew as years went on, and by the 1960s Laverda was producing smaller singles and larger twins. It was the quest for power and speed - not to mention competition from within Italy as well as Germany and Japan - that led to the development of the famed triple.

More compact laterally than the Japanese fours or BMW boxers, the Laverda triple featured a 180 degree crank which put one piston at top dead center and two at bottom. This gives these bikes a characteristic lumpy feel at idle, with some vibration spread across the rev range. With 1,000cc power is rarely lacking, and although a bit tall by today's standards, the compact width aided in packaging and handling.

The Executive is the range-topping model of the 1000cc RGS line up. The differences between the Executive and the standard RGS: Fairing extensions that protect the rider's hands on cold mornings, the bars sit higher than on a RGS to provide a more comfortable sport-touring stance, but it is really all about those fabulous, color coded hard bags. Offering usable capacity in a highly stylized format, the bags on the Executive really make this model stand out. The initial run of Executive models came straight from the factory (with a special VIN to match), while the rest were dealer-added kits. Today, due to the fact that the base of an Executive is a stock RGS, many additional "Executives" exist than before - after all, these are all just bolt on bits.

From the seller:
The Laverda factory, back in the day, thirty years ago, sold a handful of RGS models badged Executive into the USA. They were silver in color. A very very small number survive. The following year, the factory decided to enable USA dealers to add the Executive bits to the RGS themselves by providing the various parts.
Not many of those survive either. This bike for sale is one of the latter. It is not one of the tiny few original silver factory built Executives. It is an Executive built by a Laverda dealer, somewhere in the Eastern USA (I bought from a collector in the midwest, a decade ago). Still rare, not silver.

From the seller:
Folks this is for a real nice example of a Laverda RGS Executive. If you are here you know what this bike is. I have had in my collection, finally had it professionally restored last year to mint condition. Recent injuries have curtailed my motorcycle interests, and several bikes such as this will be going up for sale.

The restoration included a complete tear down to frame. Frame refinished. Engine rebuilt completely with new rings, valve job, new horns, badges, whatever it needed. Of course, all new gaskets, etc. These efforts ran over $7K.

Forks rebuilt with RaceTech gold valve emulators. Back shocks are custom made RaceTech with black springs to look vintage. Forks and shocks cost over $1000 in parts alone.

Also, bought a Keihin flat slide carb. kit at the Laverda rally at MidOhio in 2008 and had installed and then dyno-tuned. This cost $2K. Not a small effort--and kept the original air box. Works like a charm. Have original carbs.

New tires, although over 5 years old at this juncture. In pics, striations on the dash plastic are reflections of light, plastic is perfect.

All the bayflex is in mint shape on the bike, a testimony to Massimo Laverda.

Wheels are in nice shape, to make the thing museum would need repaint. My goal was to make this bike my daily rider. Not to be.

The only issue of any moment is the tacho drive is inaccurate. Wolfgang has a resistor fix inline.

All in all, a really nice Executive. Not common in the USA, and the ones out there are pretty thrashed as the Brits say. This one is not, and has been meticulously restored to boot. Needs nothing.

So, do the math. You can buy a base RGS, non-executive for around 9K. Executives are rare so pricing is TBD. I have over 10 grand in costs in this bike.

From the seller:
I had a couple senior moments listing this. One, the carb kit is a Mikuni. I should know better, but I often confuse Keihin and Mikuni. I am not a Japanese bike enthusiast. Also, the back shocks I had custom made by Worx. Cost even more than stated. I think they were over 700 each just for the rear.

More facts:
RH throttle housing is a NOS suzuki part to operate the mikuni RS 36 carbs
brake and clutch hydraulics are all new with the hoses being stainless
it also has jota pistons, a DMC ignition and 530 chain conversion
frame had the headstock strengthened with add'l gussets

This Executive model has 26,820 miles showing on the clock - high from a collectable standard, but not out of line with the age of the bike. This seller has done a lot of work to bring the bike up to this standard, and from the pictures it certainly looks the business. Bidding has been moderate on this one: at the time of this writing the auction was sitting at $9,100 with a few days to go. At that price, somebody is going home with a beautiful bike very soon. Executives are $8-$10k bikes all day long. This one is in better than average condition, and I predict that the final price will reflect that fact.

Lime Green Meanie: 1973 Kawasaki H2 Road Racer

Lime Green Meanie: 1973 Kawasaki H2 Road Racer

It has been a good couple of weeks for fans of retro stroker Kawasaki's.  This is the second nice build that has found its' way on to Ebay.  This one is a little more menacing than the first.  It's a nice mix of new and old and is someones take on a H2 road race bike.  It looks like an extremely clean build.

The damn thing looks dangerous sitting still.  Maybe it is just that odd number but a triple just makes me clinch a little more.  I'm sure the road race purists know there was a H2R (KR750).  They were purpose built race bikes and command quite a bit of coin today.

Simply nasty sounding.  Can anyone comment on the different spec levels on these KR750's?  Were there customer bikes and full works bikes?

Here is the story on the machine:



145+ horsepower.  Hang on tight!  Does it go from 35HP to 145HP in 1500 rpm?  Twist that throttle gently my friend.

The seller has placed a BIN of $15,500 on the bike.  I will be the first to admit I don't have that kind of money to drop but that really seems like a decent price considering what you are getting.  If you've ever had anything custom built you know it starts to add up quickly.  If you are tempted, click here.

Rare Honda NS400 triple 2 stroke from down under..

 In its classic Rothmans Livery from Freddie Spencer era, these bikes are rare and this is special since it retains its full originality. Personally, it would not be a favorite over an RGV500 or RZ500, but it definitely brings back memories from the 80s for about half the price. This particular bike has been ridden as opposed to being a display piece that we come across occasionally.  So, for a true collector, this would not be the bike if mileage is of concern. However, for a 2 stroke enthusiast that wants to enjoy it on the streets, it is a great buy.

Pictures reveal that this bike has been cared for:

From the seller:

This is as close as most will come to owning a a real NSR500 MotoGP bike.  In 1983 Freddie Spencer, riding for Honda, became the youngest 500cc World Champion. In celebration, Honda released this NS400r road-going replica for a short 2 year run during 1985-1986.

This is an all original, mint condition, fantastic running example of this triple cylinder, two-stroke breed. All components operate as they should including electronics, fuel system, brake system, and engine/transmission. This bike features all of the almost impossible to find parts that adorn its chassis. This bike normally starts with one kick then roars to life. The engine has never been apart and is in stock trim from its aluminum frame, triple-cylinder engine, multi-piece composite wheels and swoopy glasswork, right down to its Rothmans decals. Bike comes with original toolkit as well. An absolute must have for any serious two stroke enthusiast.

Youtube video of the bike running:

Connection to MotoGP and 500s are distant although Honda may have released this road going replica in its 2st 3cyl model to commemorate it success in GP racing. If that is what you are looking for, the 2stroke V4s are the way to go - however they will not be in this price range. The price looks about OK given its originality and the miles [folks - this bike is from the 80s and its original paint looks amazing]

Transformers Among Us? Two 2007 Benelli TNT’s W/0 Miles

Transformers Among Us?  Two 2007 Benelli TNT's W/0 Miles

Am I wrong, don't these bikes look like the were specifically designed for the Transformers movies?  I'm not sure I'm a fan of the styling but I do like designs that aren't cookie cutter boring.  The word that comes to mind is "subtle" or should I say the lack of any subtly.  The styling on these bikes is as subtle as a punch in the mouth.  Maybe a nice alternative if your local hang out is over run with Monsters though.

I guarantee you will see one of these bikes in a Sci Fi movie someday.  Like me, I bet you haven't read up on what the TNT line includes.  For the 2010 model year there are actually four models of  TNT and they can be seen here.  These two are a left over 2007  TNT and TNT Sport.  From what I can tell they only differ is slight suspension and brake tweaks.  Both house a version of Benelli's healthy three cylinder engine.  A trip around the internets provided several reviews on the TNT.  To sum them up:  great motor, decent suspension and suspect electrics.  Styling of course is in eye of the beholder.

Here is an overly dramatic look at the Cafe version of the TNT:

It looks much more plastic compared to the Tornado Tre. 

If you are one to think outside the box a bit and like what you see, these two bikes are being offered at roughly $5,000 off list.  They are both dealer bikes so I would guess with some haggling you might even do better.  They are offering free shipping  as a nice little bonus.  You can check out the and the .
