They've been talking about making one for the road for ages now but still can't find any suppliers. Anyone know when or if they'll be available?

Im sure if they don't already come road legal you could make it road legal. https://www.hdtusa.com/

But I dont really see why you would want a diesel bike

low down torque surely... Rolling Eyes

You mean those military ones?

They were offering them for sale at one point but they were REDICULOUSLY expensive. In the region of US$20-30,000 as I recall. Which is a shame because I would have liked to have one too.

Not sure if they actually did sell any though.

Hi

Don't have a boat so have no need for an anchor which would be the main reason to buy a diesel.

Horrible things with no ability to rev and stuff all throttle response. Only plus point being they have plenty of low down torque but it is hardly difficult to change gear.

All the best

Massive MPG, long engine life. No more ignition wiring and faults thereof.

they are also heavy, sound horriable aud only good when they are huge with massive power and in a beast of a 4wd truck!

yeah you wont get any ignition problems but you will get all the diesel problems and they got no real advantage apart from the military were having 1 type of fuel needed for all vehicles is usefull.

Hi

MPG would be nice, but not prepared to put up with a dodgy power delivery. Far prefer a 2 stroke with worse fuel consumption.

Engine lives of diesels are shrinking. Plenty of modern diesel car engines go pop at fairly low mileages.

As to being simple, they still need a hideously complicated and expensive injection pump and a turbo to get any reasonable amount of go.

All the best

Power output begins at 80bhp and 165 foot pounds of torque, BUT, a bit of remapping of the engine controls increases this to 120bhp and 250 foot pounds at 5500rpm! The bike weighs 450 pounds

I`m all for evolution Razz

By the way, i read somewhere else that when in its 80bhp / 165lb ft guise, it returns 80mpg.

Peak Torque on my Bora is at 1900 peak power is at 4000.

Diesels have come along such a long way, wouldn't mind seeing the sheer torque offered from one on a bike if the actual units wern't so heavy. Then you'd get the boys doing remaps.

Closest thing I can think of to a torquey, vibey, smelly, rattly, argicultural diesel on a bike is something like an underpowered, 'torquey', low revving v-twin.

Like a Harley.

At least some people think they sound nice.

The only nice sounding diesels are whisper quiet.

No thanks.

think how noisy it would be if someone didn't service it.

you ever hear those white van men terrorising the streets with there racket lol

Id certainely have a ride on one to see what it is like? Im not against new technology or idea's and a deisel bike engine is something as yet un perfected and still has alot of potential for being improved and developed further. Maybe 2 stroke deisels are the best type of oil burners for a bike, as i expect they would be smaller and lighter than a 4stroke unit, and give at least the same power or more!

The development of the 4cylinder petrol engine for sports bikes, cannot go much further now surely? There is little progress or gains to be found now in this engine format and type. Look at 600cc sportsbikes for example. They often make 2-4bhp more with every new generation of machine, but along with that peak power gain, engine speeds rise, power delivery gets more and more peaky, and low down torque and midrange snap throttle response dissapears! That's not Progress, it's just making machines more and more difficult and involving to ride, and ultimately less road useable and more track focused. Even Moto GP bikes and the 500cc GP bikes before that, were not always being developed for more and more power each season, as teams and riders realised a long time ago that making a bike easier to ride, and more useable will always reduce lap times, than an ever higher bhp figure at a meaningless engine speed, and the big sacrifices in rideability that go with it.

I think people are getting lost in the whole performance issue.

If I got a diesel bike, I wouldn't expect it to go particularly fast or accelerate particularly hard.

I WOULD expect it to go anywhere, carry lots of luggage without feeling like it was loaded down, have a massive range and run all day long.

I reckon the bike in question would do that.

Horses for courses, if I were comparing bikes to cars, I would call that bike a Toyota Hilux. Excellent cars for their purpose but hardly speed machines.

Imagine a diesel CG125

CG125TD

fuel tank only needs filling at every service.

Would be nice after my tuned dipsomaniacal GSXR.

I saw that thunderstar run in Holland, it looks ok I thought, good effort. Claimed to return up to 120mpg, based on a modified VW Lupo TDi engine, more torque than a Triumph Rocket 3, i doubt it'd beat petrol superbikes off the lights but overtakes and high speed cruising would be great!

Reasons I want one are as stink wheel says.

+

I can run it on homemade biofuel or with a bit of tinkering vegetable oil. Cheep!
Since my last incident I realised the freedom of the bike is far more important than the rush and adrenalin.
I can't imagine a better bike to go incredibly long distances in bad conditions/ road. It's what it was built for.
I like the idea of being able to cross a desert if I wanted to.
It looks really good as well, especially with a bit of rust/dirt!?
