The following is Richard Monson’s classic motorbike collection:
Kawasaki Mach IV H2 – 1972 Two Stroke Triple – SOLD

Seriously sort after the Kawasaki H2 750 triple is a fantastic bike, it looks amazing has outstanding performance for its years and is a real head turner. This is a great example coming over from the dry California climate and undergoing only very light restoration. Its was the big two stroke to be seen on in the early 1970’s and was to be treated with great respect, hence its name “The Widow Maker” One journalist called it evil, wicked, mean & nasty after a test ride. The most powerful H2’s were the 1971 and the very early 1972 models of which this is one. As Kawasaki said in their 1972 marketing brochure “We’ve just pulled a fast one on the competition. Named the Kawasaki 750cc Mach IV. Of all the world’s production models, it’s the fastest thing on two wheels. Faster than any Suzuki. Faster than any Triumph. Faster than any BSA, and Honda, anything”
After much deliberation, I sold this lovely example of the most powerful H2 as I just wasn’t using it, here’s to hoping the new owner enjoys it as much as I did!!

Suzuki GT750A -1976 Two Stroke Triple – FOR SALE

Far more sedate than the Kawasaki H2, Suzuki’s GT750 (Kettle, Boiler or Water buffalo as its sometimes called) just had to have a place in the collection. The other big 1970’s stroker with its truly advanced water cooling system, for its time, is an amazing bike, full of character and charm. Its a two stroke motorbike that rides like a 4 stroke, lots of talk from way down low, but if you want to really go for it, it has the power to oblige – as you would expect from a 750cc two stroke engine. It benefits from a comfortable riding position, good fuel consumption and sophisticated power delivery. This model is a GT750A which was the penultimate model made before the shutters came down on the big two strokes. The gearing was raised (again) for the 1976 GT750A and it also got the benefit of a lockable cover over the fuel filler cap. One of the collection favourites!

Honda CB750 Four K6 – 1976 Four Stroke Four – FOR SALE

You just couldn’t have a little collection of Japanese 70’s classics without the Honda CB750 four. The motorcycle infamously renowned for bringing the British motorcycles manufacturing industry to a grinding halt! Quoted as perhaps the most important motorcycle of the 20th century, four cylinders and single overhead cam unheard of in 1969. The bike is considered to be the original super-bike because of its extraordinary features, a large cc motorcycle that combines speed, luxury and reliability at a low price. They are still lovely to ride with lots of smooth power through the rev-range. This is the K6 model of 1976 in Candy Antares Red which has also been imported from the US.

Yamaha RD400F – 1979 Two Stroke Twin – FOR SALE

The ultimate 1970’s rogue’s bike, a mad 400cc two stroke twin designed to make the hairs on the back of your neck stand up, open the throttle and watch the front wheel go skyward at an alarming rate! The Yamaha RD400F was the last version of the air-cooled twin two stroke developed, excluding the limited edition Daytona, giving way to the RD250 & RD350 liquid cooled (LC) – The RD400 is significant for sporting the first ever cast wheels on a production motorcycle. They had been available as an optional extra since the bike’s introduction but in 1977 they became standard fitment. Coupled with the trademark coffin-shaped petrol tank and (in 1977) a rear cowling, the Yamaha RD400 oozed attitude and appeal and was renowned for seeing off far larger bikes of the time!

Honda CBX1000A – 1979 Four Stroke Six

Following on from Honda’s RC series race bike of the 1960’s they developed the big CBX1000 six cylinder monster, as their first 6 cylinder production road bike. With an advance DOHC 24 valve six cylinder engine, it was sensational to look at and fabulous to ride. Honda’s objective was to produce the fastest production motorcycle in the world and they certainly achieved it. A review written in 1978 stated that the engine was the nicest to ever to reach the street. The Benelli 750 was the first 6 cylinder and was produced between 1972 and 1978. This is a nice example of a CBX1000A again imported from California’s lovely dry climate. It rides well looks great and is a must for any small collection. The CBX1000 still feels quick today with ultra smooth power delivery and a fabulous sound, its a real treat to ride and handles remarkable well for its size.

Honda CB900F – 1981 Four Stroke Four

Labelled by Honda marketing at its introduction in 1979 as “a thundering Super-Sports bike with devastating performance and an unwavering stamina” the CB900F was a natural target for my collection. It took head-on the main competition at the time, Suzuki’s GS1000, Kawasaki’s Z1000 and Yamaha’s XS1100 and was revolutionary as the first four-cylinder, 16 valve motorcycle to hit the streets. Designed completely for the European market much to the disappointment of the US, where it was only later released in 1981. Due to a strong frame, handling is excellent by 1980’s standards and with a powerful 95hp engine it was proclaimed to be “arguably the best Honda had built for the street” and referred to as the ultimate statement of air-colled technology. Standing quarter in 12 seconds and recorded in one test at 11.84 only fractionally behind its big brother the CBX1000, and on to a top speed of 135mph, impressive. The CB900F has a slightly sportier riding position than the CBX, with narrower clip-on bars and foot position further rear, but is still comfortable for long periods. All in all a lovely bike, fun to ride, fast and a very useable classic!

Honda CRF450X – 2015 Four Stroke Single – FOR SALE

I bought my Honda CRF450X for some off road fun. I had plates indicators speedo etc added to allow me to use it on the road and hunt out those green lanes. It’s a perky bike with lots of power on tap and great fun to ride. The aftermarket exhaust sounds superb. Sadly Buckinghamshire has very few green lanes to take advantage of which has created a very idle machine! An outing to Salisbury plain did allow it to show its potential so more to be planned.

Suzuki GT250 x7 – 1980 Two Stroke Twin – FOR SALE

Branded as “The new Ton-Up Suzuki X7 the first 250cc to break the 100MPH mark!” Having owned one at 17 it was a must for my collection. I was very surprised at how tiny the bike is having not sat on one for 35 years and grown slightly! Lovely bike to ride, good brakes and a very nice sounding motor. A snippet from a reports reads :
“The X7; the lightest, most agile and therefore fastest of the pack? That’s a well-travelled argument. It was 1978 and many teens facing the 1980s would blame the X7 for prompting changes to the 250 laws when straight out of the crate a GT250N X7 was recorded at 100.5mph by Motorcycle Mechanics at Chobham’s test track. By 1981 the two-year probation and new 125 learner laws spelt the beginning of the end for the blue haze brigade; although the LC would put the final boot into Suzuki’s X7. Up until 78 all was perfect in our world, we had machines that were more than a match for any 400-4 stroke and we hadn’t even considered taking any type of exam. What remained of our oil splattered L plates hung on grimly to the rear mudguard and we spent our lives just being a nuisance; looking back it’s no surprise those in power moved the goalposts. It wasn’t all great in the motorcycle world, for as the X7 arrived Triumph Norton Villiers was liquidated, Barry Sheene lost out to Kenny Roberts at the final (German) round of the season and musically the year began with Mull of Kintyre as number one and ended with the Village Peoples YMCA; little wonder screaming around the streets at all hours had so much appeal”
