This KLR diesel engine powered bike is a US Military issue for HDT-RMCS (Hayes Diversified Technologies-Royal Military College of Science). I actually remembered to write this article after many sites has posted about the the Diesel Ducati which is a collaboration between the fashion brand, Diesel and Ducati. I thought at first it is the diesel-powered Ducati. But then, there is actual bike using diesel engine like this one that is made for military on which is based on the production Kawasaki KLR 650. 

What is even better is that this bike is equipped with bullet-proof tyres. And I think this is the ultimate puncture proof tyre for now that I know (if you know better, tell me in the comment).Using diesel is good since it is cheaper than the petrol and gives more torque for the bike. This mean that it can pull easily from stationary up to its optimum RPM.

There are some disadvantage of using diesel engine to a bike. One of the deterring factor is the weight. The engine needs to accommodate the high compression of the piston inside the combustion chamber. The other factor is about the narrow powerband of the diesel engine that makes it need to use a lot more gear than normal bike to make the bike comfortable to ride. If you look at bus engine RPM, you can see that the maximum RPM is only at 6,000RPM. Normal petrol bike have maximum power output at 8,000RPM.
