Still-Boxed Straight-Six: 1981 Honda CBX

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This uncrated “1981 Honda motorcycle” could be nothing more special than a CB200 based on its seller’s description, though we immediately recognized what’s visible through the disintegrating cardboard box as an exotic and desirable straight-six CBX. The provided frame number (JH2SC0600BC301688) also confirms that the bike in question is indeed a penultimate model year example of Honda’s flagship bike of the era, a bike most memorable for its incredible twin-cam, 24-valve, 105 hp 1047cc straight-six and the otherworldly sounds it produces. The seller says very little, though they do believe the bike to be complete apart from its title–this won’t necessarily prevent one from getting the bike on the road for the first time, though unused or not, it’s still going to need some mechanical TLC before you’d need to worry about registration. Find it here at Obenauf Auctions Online near Chicago, Illinois with no reserve. Special thanks to BaT reader Speedbump for this submission. Photos don’t provide a whole lot of detail, but the bike does look complete as claimed. Chances are it’s going to be very dusty, and anyone serious about getting it ready for the road will certainly have a lot of brake and fuel lines to inspect and likely replace due to oxidation. The bike appears to be equipped with a full fairing, and fortunately the abundance of intact plastic wrap seen on many components should provide at least a little protection to paint and decals. Tires too are likely ready for replacement. Here’s a look at what the bike should look like once cleaned up and assembled. Here’s the crate’s shipping label–note that the bike appears to have been in Illinois for decades now. And finally, here’s Leno discussing his identical ’81 in-depth. The whole video is worth a watch, but for those impatiently waiting to hear what a long pull through the gears sounds like, go skip ahead to about 12:00.

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1966 Honda CB450 has been with the current owner for 20 years and is believed to have remained in the Los Angeles area from new. Power is from 444cc parallel-twin mated to a 4-speed transmission, and an electronic ignition was installed in 2015 along with a new wiring harness, control cables, starter, and more. Finished in black and silver over a black frame, this CB450 is now being offered on behalf of the current owner with service records since 1998, a California black plate, and clean California title. The bike features silver painted fenders and a black tank with polished sides. Some paintwork has likely been carried out in the past, and larger scratches are pictured on the trailing edge of the front fender and on one of the fuel tank mounting feet. Smaller marks are described elsewhere. The seller notes that the black vinyl seat appears to be original, and the cover is affixed with rivets. The seat carries the Honda logo across the rear panel. The mirrors have been removed, though the bike retains factory lighting and mufflers. Note the California black plate from 1966 mounted out back. The speedometer and tachometer are contained in a single gauge pod which is integral to the headlight housing. 478 miles are shown on the vertical 5-digit odometer, though the true total is unknown The 444cc vertical-twin is paired with a 4-speed transmission and is equipped with dual 32mm carburetors.

An electronic ignition conversion was performed in 2015, and a new starter was also added along with new cables for the throttle, clutch, front brake, speedometer, tachometer, and more as detailed in an attached invoice. Records since 1998 are pictured in the gallery below, and a reprinted copy of the owner’s manual is also included.

No Reserve: 1982 Yamaha XJ650

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1982 Yamaha XJ650 Maxim is powered by a 653cc DOHC 4-cylinder with a 5-speed transmission and was modified by a previous owner with a bobbed frame as well as a replacement seat, handlebars, instruments, shocks, and exhaust system. The bike was purchased by the seller a year and a half ago, and subsequent service at O’Hanlon Motorcycles in San Fransisco, California included a valve adjustment, carburetor rebuild, rewiring, and oil change as well as replacement of the valve cover gasket, intake manifolds, fuel hoses, fuse assembly, and relays. This XJ650 is offered at no reserve with recent records and a clean California title in the seller’s name. The fuel tank and front fender are finished in satin green, while the engine case, frame, and wheels are painted black. The rear fender has been removed and custom side covers fabricated from sheet plastic. Superbike-style handlebars wear bar-end mirrors, and adjustable gas shocks are fitted. The frame was cut behind the shock mounts, with the resulting openings filled with shotgun shells. An LED tail light is mounted below the custom seat, and the license plate has been relocated to an axle mounted bracket. The instruments have been replaced with a digital tachometer as well as a smaller 140-mph speedometer that houses an odometer showing 1,500 miles. Approximately 500 miles have been added by the seller, with total mileage unknown. The stock headlight is wired for only a low beam setting and is fitted with custom turn signals. The 653cc DOHC four produced 73 horsepower in stock form and transmits power through a 5-speed transmission with shaft drive. Work under current ownership included a valve adjustment, carburetor rebuild, and rewiring along with replacement of the valve cover gasket, intake manifolds, fuel hoses, fuse assembly, and relays. The seller mentions that as an air-cooled bike, extended rides will occasionally cause it to run hot and the RPMs will rise. Debris is also said to enter the fuel system when the fuel tap is in the reserve position. A 4-into-1 exhaust system flows into a megaphone muffler. The carburetors were re-jetted, calibrated, and synched for optimal performance with the exhaust. Records for the recent work will be included along with several from previous owners.

BaT Event Coverage: 3600 Miles on Pre-1929 Bikes @ Motorcycle Cannonball

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

We’re grateful to BaT reader wallyworldmt for the following photos of this year’s Motorcycle Cannonball, a grueling, fantastic sounding event for riders of bikes built before 1929. The route for 2018 stretched 3,600 miles between Portland, Maine and Portland, Oregon, which would be quite a distance to cover on even a brand-new, fully-faired, heated-handgripped Honda Goldwing, let alone on a 100+ year-old single-cylinder, hard-tail, bone-shaker with a leather belt final drive and bicycle pedals for starting. Here’s what he had to say: “This year’s Motorcycle Cannonball, which ran from Portland ME to Portland OR, passed through Montana last week. These are all pre 1929 motorcycles and covered just over 3,600 miles in 15 days. The oldest bike was a 1909, which dropped out prior to Montana, but the oldest still running was a1911 (#9). Being from Montana, I couldn’t pass up the opportunity to shoot some photographs.  I have enclosed a link to the photo shoot I did during their run from Billings, MT to Great Falls, MT last Wed. I thought it might make a good feature for the BaT readers. If of any interest, pick and choose any you would like to publish on the site. Thanks for your consideration.” We’ve included them all here, Wally. Thanks again not only for the excellent photos, but for putting another cool event on our radar screen too! Photo Gallery

No Reserve: 1964 Sears Allstate Moped

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1964 Sears Allstate Moped was purchased by the seller one year ago from the daughter of the original owner. The bike was used primarily at her father’s Northern Idaho summer home and was in storage for several years before the seller discovered it. Powered by a 49cc 2-stroke single paired with a 2-speed transmission, the bike remains largely as found, though the carburetor and fuel line have been replaced. This Allstate is sold with the original carburetor, a new fuel petcock, jetting kit, and fuel line, and is now being offered at no reserve in Idaho on a bill of sale. Manufactured in Austria as the Puch MS50, Sears rebranded the bike and added it to their Allstate line of motorcycles. 1964 was one of the few years for the blue and white color option, and the finish on this example shows age-related chips, scratches, and fading. The decals are also flaking around the edges and the chrome shows minor pitting. A chrome parcel rack is fitted, and the seller believes that the black vinyl seat may be incorrect for this model. Shifting is performed by twisting the left-side grip. Details include correct grey-colored Magura grips and control cables. The speedometer indicates 940 miles. The fuel tank was stored dry and is reported to be clean inside. The original cap is provided and features an attached oil mixing cup. The chrome rims are peeling in areas and have been touched up with chrome paint. The tires are believed to be original and should be replaced. Power comes from either pedaling, or a 49cc 2-stroke single paired with a 2-speed transmission. When purchased, the carburetor was incomplete so a replacement item was sourced. The seller reports that the fuel line was also replaced and the carburetor was jetted for higher elevation so the bike runs best with 3/4 choke applied. The muffler shows minor signs of corrosion, and the fuel petcock is noted to leak as the lower fitting is missing. The seller is willing to deliver up to 500 miles, or assist with the shipping process.

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1975 Suzuki T500M Titan was purchased as a project by the seller five years ago and subsequently rebuilt in the style of a period cafe racer. Power is from a 492cc 2-stroke twin featuring oil injection and a 5-speed transmission. The body wears a modified Yamaha XS750 fuel tank, aluminum seat, clip-on handlebars, and rearset foot pegs, while engine work included an overbore as well as installation of new Wiseco pistons, an electronic ignition, and custom stainless expansion chambers. This Titan is sold with records and a clean Wisconsin title in the seller’s name. The fuel tank was sourced from a Yamaha XS750, modified with dual Pingel petcocks, and finished in lime green metal flake and metallic charcoal grey with pearl white accents. The stripes, number plates, and Suzuki logos on the tank were hand-painted by a local artist. The frame was reportedly stripped, de-tabbed, and braced with 3/4” DOM tubing before being powder coated silver. Remaining surfaces were polished or rechromed throughout. RK Excel wheels were fitted with new spokes and Avon Roadrider II tires. The axles and bearings were replaced, and the front and rear drum brakes feature new cables and EBC shoes. The rear swingarm was upgraded with ball bearings and brass bushings. The forks incorporate exposed springs, a chromed headlight bucket, and clip-on handlebars with upgraded controls. Instrumentation has been removed, but 4,500 miles were reportedly indicated when the bike was purchased and the seller estimates that 300 miles have been added since completion of the build. The seat was made from aluminum and upholstered in black vinyl with contrast stitching. X-Arc Duo rear lights use yellow and red lamps and function as running, stop and turn signal lights in one. The 492cc 2-stroke twin produced 47 horsepower in stock form and features oil injection. The engine was split, overbored, vapor blasted, polished, and fitted with new Wiseco +1 pistons as well as an electronic ignition, and a NOS oil injection pump and lines were fitted. A custom wiring harness was fabricated and new gears were installed in the 5-speed transmission. The stainless steel expansion chambers were custom-made by Higgspeed in the UK, and the polished billet aluminum rearsets are from Titan Performance. A video detailing the features of the bike is provided above, while a cold start is demonstrated in another clip here. The bike was also recently featured on Silodrome.
