Topic Approved.

I Also heard of a 800cc Triple Cylinder Diesel bike, that made just 54 bhp, but its Torque was way high at 150 NM. This was sometime back in 2007.

Say if a 800cc gives 50 bhp, what do you expect a 100cc to give? 4-5 bhp at the most ...? Moreover, Fuel Injection is a costly technology, but a compulsory one for Diesel Engines.

You see, such engines are very torquey, and can't give a relatively high amount of power for a particular cc, compared to Petrol Engines. Although for Cruisers, it makes sense though.


BTW A guy named Balu is changing the world with his Diesel & Bio Fuel Enfields, with his group Bulletwallas... See this site:-->

The World According to Bulletwallas: April 2009

He says that the guys at Enfield are not supporting him, despite a great machine & plan... So, I guess it won't make it to production ...

there was a commercial diesel engine bike that was launched in the 90's or 80's..just seen one,don't know the manufacturer..it went past and i thought that a tractor had passed..just turned my head to go ...diesel engines require a lot of money and r&d and turning them into bikes is not economically sound...also they require a lot of maintenance and pollute heavily..and apart, hardly produce any power compared to their weight...may be dats y no super car has diesel engine but suv's do coz of their torquey nature...
And not to forget the sweet massage that they would give to ur wrists...we cry for apache being so vibey,wonder wat wud u do regarding them

PS: there's no honda in the poll...

A company in Germany has developed a Turbo Diesel based bike. Its called the Neander and is one of my dream bikes.

Take a look at the link below.

Royal Enfield used to produce diesel bullets called Taurus. You'll find them in the rurals around Coimbatore and Harayana. The engines were Greaves engines, and much of everything else was directly from the Bullet.

Cheers!

The Royal Enfields used to make Diesel bulls.
We had 2 of them at home. My dad and his twin brother. one each.
Both were sold off at a later stage...
I've ridden them, God they vibrate like crazy and trust me they will definitely make me impotent.
But the mileage was so so high...!!!

A diesel engine will be great on a bike. Hope some maker comes up with this.
The tech involved in modern diesel like the common rail direct injection is quite expensive, however with series production it cam be brought down.
A 500cc diesel with a turbo and common rail injection is easily capable of over 50bhp. Thats already 100bhp/ltr. And they'll produce enough torque to scare you.

Why doesn't the poll contain the Royal Enfield name? After all there used to be a Diesel Bullet available! Maybe another one could come up with better technology!

IMO
i hate diesels no matter how much torque they produce . they are powerful only because they are turbocharged . drive a non turbo indica and you will know . if you take two 2000cc engines one petrol and one diesel . turbo them both . no prizes for guessing which one would make more power .

if you think from a non-enthusiast's point of view yes it makes sense .

Diesel engines have a very high compression ratio n so the engines have to be very sturdy (Read:Bulky).
Moreover, people here complain abt the vibes in RTR. Imagine wat will they say if they ride a diesel engine...(those who have ridden the diesel bullet aka Taurus will know what im saying) for those who haven't, imagine a 2 wheeled Tractor
starting the bike takes a lot of efforts....even the guys weighing 70 odd kgs will find find it hard.. so forget abt the others..Starter motors will be a lot heavy (read: Costly)

now talkin abt the recent technology in the Diesel engines, they have not reduced the Compression Ratio so that the engines can be made light weigh (compared to Petrol Engines) the Modern Diesel engines are light weight but only compared to their predecesssors...they are still considerably heavy.
Cold Starting a Diesel Engine is really a pain in ..... even the modern Diesel Engines are not as impressive as compared to the contemporary Petrol Engines.
The Torquier single cylinder mill will never ever be a smooth running mill it will have to be a multi cylinder (say inline or flat) this again will increase the COST of the bike..
A heavier Engine will also need a Stiffer Chassis, so more weight...


So now would u like to use a CHOTA HAATHI (BABY ELEPHANT) that doesn't move fast and also gives u more tremors than what the most powerful Earthquake wud have ever given????????

naaaaaaaaaaa...

But there is a Positive side of this too...
the Fuel Efficiency will be Rocket High...yup u guys read it correctly...
the Diesel Bullet used to deliver approx 70kmpl

lol .......

Instead of Diesel bikes, manufacturers are going towards LPG and CNG bikes. Bajaj and TVS might be coming up with such bikes in the near future.

RE had a diesel bullet for sometime with a greaves engine on it (same mill that our kissan bhais use to pump water, also a very efficiecent generator set :P). The tagline for is a bit of a take on the Old hero Honda line of "Fill it, write the odo reading on a piece of paper, shut it and forget it" lol!

Pfff It was everything that I dont like in a motorcycle heavy sluggish slow sounded like well a water pump/DG set.

Diesel is a great fuel but to power ships:P ... but bikes nah!
