Boots Langley: Building Kawasaki Triples for the 21st Century

Boots Langley's Kawasaki 750 Triple Ultimate Cafe Racer is rocking...

Boots Langley has been a fan of Kawasaki’s two-stroke, three-cylinder bikes since 1973, when he first bought a brand-new H1D 500. ‘Today, I can build you a 2010 Kawasaki H1 or H2. What I mean by that is, I build not only a freshly restored bike or engine, but it's now designed to run on today's 91 Unleaded fuel,’ says Langley on his website.

The bike you see here is Langley’s Ultimate Cafe Racer (UCR), which he says he is the best triple he’s ever built. ‘It is the culmination of over 16 years of building and rebuilding my 1973 H2 750. You see it in its 4th reincarnation,’ he says. The spec is pretty impressive – the two-stroke three-cylinder 750cc Kawasaki engine produces 90 horsepower, the bike rides on 18-inch magnesium wheels from a TZ750, brake discs and callipers are from a TZ250 and GPZ550, the 43mm adjustable front fork is off an FJ1200, the aluminium swingarm is from a GPZ750 Turbo and the fuel tank is from a KR750.

If the medley of parts from half a dozen bikes don’t get your attention, the paintjob definitely will – Langley has had the bike painted in DuPont’s ‘Hot Hues’ Urethane paint with custom graphics. We can only try and imagine what this thing sounds like when it’s fired up. Should be freaking awesome! :-D

Hi triple fans,
My UCR is the best handling triple I've ever built and it runs very well, being down 50-60lbs from stock, with all that aluminum, magnesium and fiberglass!!
As an FYI; you'd have to be King Kenny, to get those chambers to drag!!
I will add that it's just about impossible to get these triples, and any 2 strokes from the 60's & 70's, to run right (meaning repeatedly to red line) and not hole a piston without the 98-102 octane fuel they were designed for. Recut heads, retarded timing and rich jetting will allow pump gas, but it will still blow up if run very hard. Best to bite the financial bullet, and use the correct fuel (No av gas please. It's made for low rpm engines run at high altitude). BTW; Higher than stock compression Wiseco's require 102+ octane.
Ride safe and have fun.
cheers
