Hi everyone my name's Nick. I'm from Langen Motorcycles. I've been asked by Alex to introduce
our Langen two-stroke. So I'm gonna give you a little walk round. The stand's nice and quiet
at the moment. It's nine in the morning so it's a good opportunity. So if we start at
the front of the motorcycle you can see it's styled as a Cafe Racer but a very modern
Cafe Racer, so we've got a blend of classic styling with some very modern components and materials.
So you can see a mix of carbon fibre. Got forged aluminium wheels. Very modern suspension and very
modern rear dampers. The whole vehicle weighs only 125 kilos so we've worked really hard
to keep the style there but also pair the weight down as best we can. The engine is a two-stroke so
the unique selling point of this bike is it's a Grand Prix replica, two-stroke 250 V-twin engine.
Fuel injected, oil injected, with electronically controlled exhaust valves. So it's a very very
very strong engine and initially the character of the engine dominates the riding experience. After
you've got used to the engine you start to enjoy it. The other details of the bike really shine out
so we've spent a lot of time and effort with Ohlins and K-Tech to work on the suspension and
Hel, another fantastic British company for the braking system. So if I gradually walk you round
you can see the engine configuration. It's a V-twin. Because it's a two-stroke, we've got freedom to
rotate it around for a good mass distribution. So it's rotated forwards about 180 degrees. One
cylinder up 45 degrees one cylinder down with the ram air effect through the the intake at the front.
We've got a trellis frame. It's a 7000 series aluminium. It's a trade secret, the wall thickness
and the outside diameter of the tube. But we spent a lot of time analysing the
stiffness of the frame to get a beautiful feel for the rider. We come round to the side
you'll see a combination of the tubes. Some bonding technology here, bolted up to the chassis side
members. And we've made a feature of the trellis to show off the beautiful machine work on the engine.
Towards the back of the bike you'll see the characteristic two-stroke expansion chambers
and the carbon stingers out the back.
And for this show we've changed the wheels from the usual gold spokes which you might have seen
on previous road tests, to the forged aluminium black wheels. We think it makes you look a bit
tougher a bit more of a street fighter and a lot of people have really commented on
how good it looks. So brakes on the bike. We've worked very close with the company called Hel.
A great British brand, provide a lot of braking systems for British superbike riders.
So these are their brakes with our custom caliper adapters so they're radial brakes
onto some right wheel up Ohlins forks. Fantastic feel. Braided lines are standard and actually
if you come round this side of the bike is a beautiful feature on the yokes. To
keep things lovely and clean on the inside of the motorcycle we've designed some yokes where we run
the brake lines through the yoke itself. So you'll see a T-piece there machined into the yoke. Keeps
it beautiful and clean and retains a fantastic feel on the brake lever. Riding position,
this bike has been designed for all different shapes and sizes of riders.
Particularly at the front where we've fitted some interesting clip-ons which we can rotate in lots
of different degrees of freedom. So if you're a taller rider you can have the thing a little bit
wider bit more comfortable. If you really want to get squat down into a low tuck position we
can move things around for you to accommodate that as well. Likewise with the suspension if you're a
taller or heavier individual we can work with K-Tech and Ohins to adjust the bike to suit you.
A few other little racing touches. Lots of carbon fibre work which I'm sure you've
seen already and we've worked really hard to look at the stress analysis through
the bike and use carbon fibre where we gain most material benefit and also aesthetic
benefit as well. And on that theme you can see on this side of the motorcycle
we've done a lot of track miles with this bike in Italy and we've fitted a 415 chain which is a...
lot of people comment on how thin it looks. This reduces a lot of the rotating losses that we find
in heavy transmissions and we get a little bit of extra horsepower feel on the throttle as well.
If you're in the market for a modern Grand Prix two-stroke engine which has been tuned
for the road in a beautiful package, then this is the motorcycle for you. Whether you're taller or
shorter rider, sporty rider or road rider, we can adjust the bike to suit your needs.
