1975 Kawasaki H1 500 Mach III

Usually when I decide to post a bike that I think would be a neat addition to this blog, the bike is something I would add to my collection. That is if I had one! This bike is no exception. The power band of these triple two-strokes is legendary. Most motorcycle enthusiasts have some great tale of them, or a friend, narrowly escaping death from stuck throttles, unintended wheelies at high speeds and terrifying crashes with just a mention of a two-stroke triple. This why I am always happy to see one in original condition. If all the stories I’ve heard about these were true then there would have been more of them crashed than Kawasaki even made.

1975 Kawasaki H1 500 Mach III for sale on eBay

The seller seems to be the “real deal” with a lot of knowledge. Here it is in his words.

Up for auction from my personal collection is one of my nicest 1975 Kawasaki H1 500 Mach III’s. This H1 is not the same 1975 H1 that I sold a few weeks back and is an entirely different motorcycle so please read the description and look at the pictures carefully. This H1 has been one of my personal drivers and is an overall clean, correct and maintained example of an H1. I would like to stress the fact that this H1 should not be confused with the other H1’s sporadically offered by amateure and hobbyist sellers. It is one of my personal drivers. With so many Kawasaki’s in my collection, I have decided to let a few of my nicest examples go as I now realize I am never going to have time to enjoy them all. I am convinced the new owner will appreciate the overall quality of this very nice H1. The frame number appearing on this H1 is H1F-43469 and the engine number is KAE-113486 making this a numbers matching correct original motorcycle. The odometer currently reads 14,248 miles which is the actual mileage of this H1 and the build date on the vin tag reads 12/74.

Cosmetically, this H1 is a very clean and well maintained example.  The original body work is in overall nice condition.  The side covers do show some patina and do have a few chips but the paint is overall very presentable.  The original fuel tank is clean inside and in overall very nice original condition and is no doubt much nicer than the average H1 fuel tank. It does show some patina and sun fade but this does not detract from the overall quality of this H1. The seat is in overall outstanding original condition and features a soft and flexible original seat cover.  The rear tail section is also present and matches the original condition of the rest of the body work.  The original chrome chain guard is present with nice factory chrome and does not appear to have any visible damage.  The original front fender is also in nice original condition as well as the correct original rear grab bar.  The correct turn signals are also mounted and functioning on this H1.  This H1 also sports newer tires which ride out very nicely and make this H1 even more fun to ride.  The chrome on the original rims is very nice as well.  The original spokes and hubs are clean and correct.  The handlebars are original and do not appear to be bent and have correct Kawasaki mirrors mounted as well as all correct and original handlebar switches.  The gauges are very nice and do show very slight fading but are in well above average condition.  The headlight bucket, fork ears and headlight ring are also in excellent original condition.  The correct rear shocks match the quality of the rest of the bike.  The under seat area of this H1 is also in a maintained and original condition.  The exhaust set on this H1 is in exceptional original condition and are one of the nicer original sets of H1 pipes I have.  They are solid with no rust or other major damage and would be very hard to replace. In fact, this H1 sports the nicest original pipes of any later H1 model that I have or have had and would be acceptable on a restored H1.

Mechanically, this H1 runs and drives very nicely. It wasly starts on the first few kicks and quickly idles down.  This has been one of my personal drivers and has always been a reliable and enjoyable H1.  As with all old motorcycles, the new owner should perform some general maintance as reccomended by Kawasaki as I have not had this H1 out much this summer (approximately 2 miles put on this year).  The brakes function and quickly and smoothly bring this H1 to a stop when applied.  The original air box is present as well. The engine itself is also very clean, original, correct and well maintained.

Overall, this is a very nice and well maintained H1 that I have used sparingly that would be the perfect example to take out and enjoy or add to a collection.  Nice examples of H1’s are becoming very difficult to find especially from a reputable seller with outstanding feedback from selling New Old Stock parts and vintage motorcycles.  I also of course have a clear title as well as original Kawasaki key to go with this very nice H1.

This is what I’d call a practical classic sport bike. It’s been ridden and shows some wear but is all original and unrestored. You could slide this into a collection and have your staff dust it off once in a while or you could ride it. I know which option I’d choose. These bikes along with several others are going to be very hard to find someday soon. Collectors are already hoarding them in warehouses around the world. Save this one from it’s banishment from society and go for a thrilling ride.
