Tough Love – 1997 Suzuki GSX-R750

Not far into Suzuki’s water-cooled era, Ram Air Direct became a way to extract just a few extra ponies from 748cc, and were a nice success combined with the new-to-96 alloy twin-beam chassis.  This second-owner Gixxer looks worthy of a little TLC.

After many years of air/oil-cooled engines, the 128 hp SRAD engine had tighter cylinder spacing, crank-end camshaft drive, and even tilted forward to straighten the intake path, presented a very compact package.  Magnesium covers for the head, starter and clutch helped contain dry weight to under 400 lbs.  The frame and alloy swingarm were an eclectic mix of stampings, extrusions, and castings, and must’ve give the production welders fits.  Multi-adjustable suspension was in place front and rear, and wind-tunnel tested bodywork smoothed airflow.

After an owner who seems to have been focused on performance, this GSX-R might respond to a rolling restoration.  Complete and not much in the way of external mods, it has been kept running to a high standard.  Especially the not-so-intuitive brake modification of going to a four-pot caliper to improve feel.  A nice list of mechanical improvements from the eBay auction:

-Wiley Co. Slip-on with larger main Jets Carburetor rebuild kit.
-Steel braid lines front and rear.
-Valve adjustment is done less than 100 miles ago. 
-New Throttle cable  
-New Spark plugs 
-Replaced New fuel pump, filter, complete petcock, and base gasket.
-Replaced the OEM front six-pot (wooden feel) stock calipers for a set of newly rebuilt Nissin 4 pot with new EBC pads (100x better-stopping power over the OEM calipers).
-Replaced the OEM automatic (CCT) cam chain tensioner (known recall issues) with an APE manually adjustable one.
-Replaced the OEM Charging system, with a new stator, Regulator/ Rectifier, and battery. Charging at 14.5 volts now.
-Rebuilt rear caliper with new pistons.
-Rebuilt front forks, new seals/oil, also new bearings for the steering head.
-Racetech rebuilt rear shock new spring and cart; fully adjustable preload, compression, and rebound damping. I have added adjustable rear links for ride height adjustment.
-K/N Filter for the Ram Air.
-Battlax S21 Front and Rear tires
-Front and rear wheel bearings replaced.
-A new chain and sprocket.
-Rear solo seat cowl and passenger seat.
-The seat has been reupholstered with a back pad.
-Undertail fender eliminator.
-New Brembo 19mm RCS Radial Master Cylinder and Clutch lever
-New set frame sliders.
-Stomp Grip traction tank Pads.
-New battery

In a segment where lightness never goes out of style, Suzuki injected a bunch into the SRAD models and combined with popular pricing, had a hit.  Hopefully fans will see around the cosmetics of this example and know that the hard work of helping this ’97 survive has been done.

Featured Listing – 1982 Honda CB750F Super Sport

Tens years after the ground-breaking CB750 was introduced, Honda responded to market pressures with a DOHC update, making a solid 100 hp per liter.  Honda’s Super Sport was aimed solidly at the market, and left HRC to tune and alter the CB’s for AMA racing.

1982 Honda CB750F Super Sport for sale at Seattle Used Bikes

Ultra-square with 62mm bore and stroke, the new engine willingly revved to 9,000 rpm, where 77 hp was found.  Honda had three engines in the pipeline, and chose the smallest bore since it made for the narrowest engine and had the best combustion characteristics.  A fairly traditional twin-downtube chassis was constructed, with a riding position just slightly more forward than the original CB750.  Brakes are big, all disks, and in a nod to the 500 lbs. dry weight, the rear disk is larger than the fronts.

 

Offered by Seattle Used Bikes, this Super Sport has logged just over 8,000 miles, and has been nicely restored.  The Comstar wheels aren’t the sportiest but have endured the test of time.  Though the  bar end mirrors are cool, K&N filters and black 4-into-1 exhaust will be the most noticeable mods after the engine’s started.  Notes from SUB‘s – website –

This very clean Honda Supersport brings back lots of memories of Honda’s HRC racing efforts with Freddie Spencer in the early 80’s… This particular bike has gone through a full restoration over the past 10 years, carbs are updated to the fabulous Keihin CR Specials, a Moriwaki hand made 4-1 exhaust was installed along with K&N filters, this Honda Supersport runs and sounds fantastic!

 

Have to applaud SUB‘s tuned-in business model – service, parts, accessories, and consignment – very neat.  Ten bikes currently ( three on RSBFS ! ), and the CB750F is right in the middle of their sporty / spendy continuum ( just as Honda always intended ).  The ask is $5,199, and the cherry condition might sway a rider who’s either not interested in financing someone else’s boat payment or who recalls the Freddie Spenser era and can no longer pretend an ergonomic challenge is that much fun.  Contact Dave at (206) 535-6812 or by email – here –.

1992 Yamaha FZR600 Vance & Hines #353 And #376 Of 636

Here are two, rare, FZR600 Vance & Hines Edition replicas!

First, located in Worthington, Minnesota is #353 with 9,132 original miles.  The seller, a dealer, says that this bike is in collector condition which agrees with the mileage and condition in the photos.  No asking price or further information is given.  See the bike on Worthington Sports Center’s website here.

Second, located in Burnsville, Minnesota is #376 with 22,600 miles.  The bike has recently been serviced which includes fuel system flush, carb cleaning, and ceramic coating of the  header.  This bike also comes with the factory shop manual, tank bra, and some other bits.  The current owner is the third owner and has owned the bike since 1998.  This bike looks to be in very good condition in the photos.  The asking price is $3,000 which isn’t outrageous compared the the majority of FZR600’s out there.  See this example on Craigslist here.

I’m quite sure, from what I remember, these bikes were just replicas and didn’t feature any additional mechanical features (Other than a Vance & Hines exhaust system) as with the SJR CBR’s and Rossi R1’s–please correct me if I’m wrong.  Either of these bikes look to be in fantastic condition even though one has more than ten thousand more miles.  The choice, for me, would come down to what the dealer is asking for their bike and how much I valued a sub 10k mile bike.
