I love cars, but I really love motorcycles. Driving a fast car can feel like flying a jet. But a fast bike, that feels like flying with a cape. I’ve spent a huge part of my life on two wheels. I’ve sacrificed time, money, friendships, even my own body to bikes. But after all that, I’ve never ridden - or even seen - a diesel motorcycle. And that got me curious: Why aren’t there any diesel motorcycles? Well, we’re about to find out!

    When I was little, I know there is a " diesel conversion kit" for bicycle. A two cycle small engine, adopted to convert a bicycle from pedal only into a motorized or pedal option. I can't really remember right, but, the brand was TAZ? Very noisy and loud on the road. The year was about 1967 to 1977, if I remember it right.

    You kept showing an upright engine and complained about size and vibration. What about horizontally opposed engine(like BMW) Vibration is cancelled and size is not a problem and weight is not a problem. No reason it has to be a V twin. Beamers are excellent touring motorcycles. There is room for a turbo on it too. Definitely need an extra long kick starter arm due to the high compression. Diesel engine also runs on Kerosene....or used cooking oil from MickeyD's.

    So... What you're telling me, is, that a motorcycle like the infamous Panther Model 100, a single cylinder bike with a (surprise, surprise) 100cm stroke, build specifically to have low-end torque to efficiently work with sidecars would have been made even better with a diesel engine?

    Why not two stroke diesels then? Two stroke diesels have much better power to weight ratio. I've done some work in the marine industry and two stroke diesels aren't uncommon for this reason.

    I have gotten out of several tickets without the help of any lawyer. This actually comes from advice given to me by police officers and I know it works, because I have used it several times, and it almost always works. First off, drive safely. If you commit no traffic infractions you will get no tickets. Having a clean driving record is an extremely important part of this method. It can work if you have tickets on your record, but the more tickets you have, the harder it will be to talk your way out. Being a safe driver or rider will be of great help here. But no one is perfect, and you are bound to make a mistake sooner or later. Thing is, cops understand this. And with your DL the cop will have access to your record. Having a clean record will give merit to your words. First off, understand that if a cop pulls you over, that cop believes you did something wrong. It doesn't matter one bit if you did or did not actually do something wrong. Arguing that you didn't do anything wrong will only harm. All you are doing when you argue is telling the cop, "You suck at your job." Even if it's true, and some cops really suck at being cops, saying so will never help you. How inclined will you be to help someone who tells you to your face that you suck at your job, especially if helping them is not part of your job? If you get pulled over, you probably disserve to get a ticket, at the very least the cop *BELIEVES* you disserve to get a ticket, and that is really all that matters. So if the cop chooses not to write a ticket he is doing you a favor. If you go into the encounter with the attitude that you disserve a ticket, oddly, you are a lot more likely to not get one. In one case, when I was still a teenager (19) I got a speeding ticket. I was, in fact, speeding and the cop even lowered the speed he had me at, but not long after getting that ticket I lost my job. I went to court not to fight the ticket but to ask to have my fine reduced or to get assigned community service. The judge asked the cop what my attitude was like and the cop said it had been good. Then the judge asked the cop if there was any reason he shouldn't dismiss the ticket. I was surprised when the cop said "no" I beat the ticket by admitting, in court, that I was speeding! I saw the cop outside the court and asked him why he didn't fight the dismissal and he said when he had pulled me over he was on the fence between a ticket and a warning. He chose to write the ticket mainly due to my age, but because I had not tried to fight the ticket in court, he felt I had learned my lesson. Once, because I was not paying enough attention I almost ran a red light. The car I would have collided with was a cop car. I stopped less than a foot from them. I had to back up so the cop could proceed. He waggled his finger at me to follow and I was sure I was going to get a ticked, and I deserved it! But the cop let me off with a warning. I think that alone proves my method works. I mean nearly colliding with a cop car is usually a sure way to get a ticket.

    It's a question I never asked but still interesting. It seems like an opposing twin would be the best configuration for a diesel bike to give room for the longer stroke and to keep the weight down low in the bike.

    The thing that made Diesels popular in cars was the turbo. this was the game changer that transformed diesels from slow cars that struggled to reach highway speeds in to cars that could easily keep up with Petrol cars. on a motorcycle a turbo is however a whole new can of worms, as it is quite difficult to find room for all the extra plumbing, coolers etc. There is a good reason why in the 80's a few brands had a try at making a turbo bike, and they all stopped. Also on a bike turbo lag is a lot more unwelcome than in a car (turbo boost somewhere in this corner). So easy to see the problem with a turbo Diesel bike. Mind you, I think the Trek had a turbo Diesel from a smart car if I am not mistaken. But is was a big heavy and expensive bike.

    Diesel bikes are pretty much a waste of except in places like India where they were sometimes produced. The sole reason for military diesel motorcycles (also a waste because they fail to be quads which means no cargo capacity or ability to tow or ability to evacuate wounded troops with a wounded rider) was the Common Fuel Concept which got rid of (extremely dangerous in combat and a monumental logistic asspain) having to supply Mogas to expeditionary units.
