Surely, I can't be alone in reading this having driven an RX-7, numerous turbos, but no diesels, thinking this is EXACTLY what I need to replace the 310cc single cylinder in my BMW motorcycle that gets 70 MPG consistently, sits comfortably at 70 MPH on the highway, but is slow on the uptake in a crowded on-ramp. I remember the BMW single being a revelation because it's a single, DOHC, eats corn gas for breakfast without indigestion and has plenty of breathing room at the top end of the tach, which is unusual in single cylinders at redline, 10.5K RPM IIRC. One can only hope since one has less-than-zero mechanical engineering skills.
- davidbanham 4y agoPeople have shoehorned diesels and wankel rotaries into BMW airhead frames. It’s possible but not for the faint hearted. With a small frame like yours you’d probably be better served by an EV conversion if you want to go down that path.
- davidthewatson 4y agoThanks for the comment. I don't know anyone who has done the rotary or diesel conversion, though I have driven the zero and know another designer who built an electric motorcycle from scratch. When I say from scratch, I mean sketches, solid works, chassis - the whole 9. Of course, this gets easier at the edges where wheels, handlebars, exhaust, lights, and batteries are abundant. My daily awareness of his progress was working close to his desk at work, so I'm not sure where it's at today though I recall he was about to transition from chassis to engine at the time - 2016. He was definitely ahead of the curve. Sadly, my skills are in things that we have the luxury of pretending are not bound by the laws of physics. ;->
