Biking multiculturalism! Some things are best left in the past eh? Let’s rewind to the 1970s and adopt the vernacular of the older British bike riders of the 1970s: “Bloody Japanese! Selling bikes over here, ruining our British motorcycle manufacturing business.” This was real: a mate once told me how his dad’s time in the Second World War meant he wouldn’t allow his son a Japanese or German motorcycle.Thankfully we’ve forgiven. The Japanese manufacturing model reinvented the British bike industry by having large, UK-based distributors over here and employing lots of people adding to our bottom line. So thank you Hamamatsu, Shizuoka, Soichiro, Michio, Torakusu and KHI! And then (of course) this all showed John Bloor and Hinckley Triumph the way to go which is why we
actually have a decent mass produced British motorcycle industry – Triumph checked out Japan and Europe before they made a start. And today? The thing is, with bikes like the Honda Britain featured in this month’s magazine all the way to the 50th Anniversary Honda CBR600s, VFR800s and CBR1100XX Blackbirds of the 1990s, we are really celebrating a fusion of like-minded motorcycling minds which crosses the multicultural divide. In a Britain that sometimes forgets that the Battle of Britain’s top scoring squadron was Polish when moaning about immigration, motorcycling revels in multiculturalism. And long may it continue!

A bargain, modern-classic with 130bhp for less than a grand? That’d be a CBR1000F then.

urtle (vb): to rush violently; move with great speed: and that’s exactly what I’m doing on Rich Gibbon’s rather tidy CBR1000F. As a self confessed aficionado of smaller motorcycles or those of an overtly lithe disposition, the big water-cooled inline four has come as something of a shock. This bike may now be a quarter of a century old but it has more than enough power to scare the living bejesus out of most normal average riders like me. The Honda CBR1000F is The Big Aitch’s precursor to the legendary FireBlade and later Super Blackbird, and if later sports bikes are your only point of reference then, frankly, you may very well be in for a white knuckle ride. Treat the bike like you would a modern motorcycle and chances are it will be in charge and you will wonder what on earth has gone wrong. With a power output around 132bhp and a kerb weight approaching a quarter of a tonne this is one seriously potent piece of kit. Contemporary road tests sometimes suggest the Honda was bland in comparison with the ZZ-Rs and Gixers of the period, but in all honesty anyone who pushed any of these machines to their limits was a hero in my book. Taking time out with the owner as we get some static shots we chew the fat and conclude that, for once, history had genuinely repeated itself. You would have thought that the Japanese industry would have learnt from its mistakes at the end of the 1970s but apparently not. Just like the leviathans at the tail end of the glam rock and punk decade, the bikes of the late 1980s and early 90s were becoming a triumph of ambition over ability. Basic frames were struggling to cope with the power output, tyres were once again being pushed to, or beyond, the limit and brakes were being worked harder than ever before. It can hardly be a coincidence that the same year our test bike was registered, the IoM TT was blighted by the deaths of Phil Mellor and Steve Henshaw among others. Both were competing in the Production and the general consensus of the time was that the rules had pushed

ekindling your misspent youth is as easy as a short blast on a classic 200cc Yamaha. The less expensive offerings in the Yamaha range of the mid-Seventies came with a secret ingredient – potency that their tiny frames could barely contain. That made the RD200 a hooligan’s joy ride. Open up in the lower gears and the front wheel would reach for the sky; power out of corners indiscreetly and you’d find yourself wrestling with the handlebars to maintain control; on the open road, good examples could leave some 250s in a cloud of exhaust haze. The RD200 was brilliant. Yet it wasn’t a bad handler; Yamaha had injected just enough power to make sure that your adrenalin levels were kept at the limit. Take a pillion with you and the excitement was cranked up even higher; just what you needed to show how crazy motorcycling could be to an impressionable bird. It all came back in spadefuls when I took Paul Turk’s immaculately restored RD200DX for a spin. This example dating from 1980 was the final version before the air-cooled range was replaced by liquidcooled singles, and it transported me back to a time when you didn’t need to fantasise about living on the edge. All it needed was a bit more than £600, or the hire purchase option, and you were on the road, ready to terrorise the neighbourhood. Of course, it wasn’t a completely authentic transformation. What was a small bike for a lithe twenty-something now feels a lot more diminutive, but the memory was just as vivid. This RD200DX delivered the thrills as much as it ever did. With its ‘coffin’ shaped fuel tank and duck-tail

ULTIMATE V6-LC! When a customer wanted a V6 two-stroke Yamaha, there was always only one person to go to. Our Stan.

ast January’s issue had the above Reboot of a new V4 RD500LC for the new generation and readers drooled at it. Just think if we could marry it up with a V6, 1200cc version of the venerable RD500LC powerplant, if only someone would make one. Well it looks like Stan has been asked to build such a motor. Take it away Stanley. A couple of years ago I built a 750cc version of the RD500LC V4. I wrote articles on the building of it in CMM. I used two pairs of 350YPVS barrels and increased the stroke of the cranks by 4mm to 54mm. At the end of the article I said that next would be the 1200cc V6! It was just a throwaway comment, although I had looked at the idea while building the 750. Then a few months ago I had an email asking me if I would build one and how much would it be! The caller was a guy called Ian Buxton and he was serious, although I told him I hadn’t really seriously looked at it and didn’t know if it was possible and I definitely couldn’t give a price. He asked if I would have a proper look at the project and say if I would take it on. I had a set of scrap crankcases and an engine that I was working on, I spent a while measuring it up and decided it was definitely/maybe possible. I checkedup with the crank specialist that built the stroker cranks for the 750 and he said he could build the cranks. I contacted a firm that make ignitions and they said they could make the ignition. I showed the cases to my welder and he said he would undertake the welding. I phoned Ian up and said it was possible and two weeks later he arrived with an RD500LC engine and a spare set of damaged cases and a large
deposit! The RD 1200 V6 was go! Ian Buxton is an ex-350LC racer from the early 1980s, he has a successful business, but instead of taking it easy, he races a Formula V car and has a Spondon RD500 based 680cc race bike (which I will be doing an article on later). Ian and I talked over a few options and ideas and decided on a very broad set of ideas to work to. As with the RD750 V4 I said I wanted to stroke the cranks to 54mm and use 350 Yamaha barrels but instead of YPVS barrels this time I wanted to use Yamaha Banshee barrels from the racing quad. Ian wanted to know what power I expected it to produce. I said that I get around 75bhp from a 350cc Banshee engine so with three sets of over-bored Banshee barrels 225bhp was possible but unlikely. Although Ian was excited at the prospect of that much power, even he was worried that it may not actually be ridable! I didn’t care, I am only building it! We agreed that although the engine would be fully tuned and would be running large carbs, race ignition and race pipes I would tune the engine for midrange and keep the exhaust ports low. The 350 YPVS barrels have power-valves to spread out the power: however, the Banshee barrels don’t have power-valves and are a race engine! The plan was to use the existing V4 cases of the donor engine, complete with gearbox and the left-hand pair from the damaged cases, which luckily were damaged on the right-hand side. I sawed off the left-hand pair on a mechanical saw, allowing myself a good safety margin to where I was going to machine them to. Next, the left-hand side of the donor V4 was machined flat then the inside of the cases where the seals are located was machined out to the same diameter as the main bearings. I then measured the distance between the V4’s main-bearings and lab seal and www.classicmechanics.com / 79
