Title: diesel track motorbike, but not a thumper
Post by: beeman on June 16, 2011, 03:25:57 PM
Was at the local bike shop and one of these pulled in. He bought it in feb and took a couple of months to register.
cost £18000 but he said gone up another 1000 euros since then.

That army diesel bike looks very interesting. I am assuming that it is this one
http://www.telegraph.co.uk/motoring/motorbikes/2715724/Army-drafts-in-diesel-power.html

I'd be happy with 80mph top speed as I don't really go that fast very often even on my bikes that can go faster.
I'd be ecstatic with 140mpg as I appear to have dwindling financial capabilities thanks to 4 kids and the delightful HMRC and impending loss of child benefit money.

Yup, that'd do me fine. And it looks nice too. Still not available to the general population yet though, as far as I know..

Hi Beeman, I met the owner a few months back in March at the start of the Round Britain Rally, I think he said he lived in Huddersfield, at first glance I thought it was a KTM, then realised it wasn't. After a long chat he offered me a ride, but I declined, as he was due to take it back to Holland the following week for it's first service. He seemed quite happy, but he said that you had to use the brakes all the time as there was a total lack of engine braking......which to me would be a concern.

Re the engine braking probably a bit like a two stroke then.  Oddly I would have thought that any diesel bike would have had demon engine braking, high compression and all that......

Engine braking is by an large caused by the engine having to pump air through a closed throttle. Diesels do not have a throttle (butterfly/slide) in the intake so the engine can pump air with little to restrict it.

Could have an exhaust brake like the Wagons !
Though I'm not sure if they are used as much nowadays....was some trouble with a couple blowing head gaskets.

They have a CRT transmission, hence the lack of engine braking. A big scooter really.

Still used, but with added electronics to stop over pressure.

The CVT is required as the power band would otherwise require an 18 speed box like the trucks too.

It'll happen, Diesels can burn everything from coal gas to cooking oil,  so a lot easier to find fuel that's not dinosaur based. That said, I'm waiting until Triumph or Yamaha launch one. The military BTW have withdrawn all theirs, their only use for bikes is outside places where people of different political views may decide to stretch piano wire across the road. If your bikes never go further than escourt duty on the A1, you can buy BMW's and Hondas and fill up at Sainsburys.

Would be nice if it resulted in lots of ex army/never made it to the army diesel motorbikes appearing for sale... somehow I doubt it though  :(

edited to add, seems someone is producing 1000cc hatz diesel urals though (for the sidecar/diesel/winter rally/german speaking type fans/nutters  ;) ) http://www.loew-gmbh.de/index_motorrad.htm

Hmmm, I'd be interested to see how the gearbox/transmission copes with the diesel's torque. The Ural/Dnepr gearboxes were originally designed to cope with 24bhp and the big problem they found with swapping engines was the gearboxes and transmission rubber 'donut' failing. They could cope OK with BMW R80 engines - 50bhp, but the R100 70bhp engine was usually too much for it to cope with.
