Greenfly: LPG power comes to motorcycles


The LPG-powered, Yamaha XT500-based Greenfly

Dave Akhurst could have found a partial solution to dealing with the high prices of petrol. No, he hasn’t made a fuel-cell powered motorcycle. Instead, he’s converted his Yamaha XT500 to run on liquid petroleum gas (LPG).

LPG costs significantly less than petrol (mostly because it’s often sold at government subsidised prices…), can be less polluting than petrol and has a high octane rating. So why aren’t all bikes (and cars…) LPG-powered? Because LPG needs to be stored in an on-board pressurised tank, and in the event of an accident, it could blow you and your passenger(s) to kingdom come…

Coming back to Akhurst’s XT500 – it’s called the Greenfly – the 500cc single-cylinder engine makes around 30bhp and delivers a mileage of 30km/l. And… er, while that doesn’t sound terribly impressive, what’s more interesting is that the bike seems to have been heavily modified, with single-sided swingarm, single-side fork, belt drive, custom-built wheels and one-off bodywork.

If he can do so much with an ancient XT500, we wonder what Mr Akhurst would turn up with if he were let loose on a new R1…!

Sorry to tell you, but Mr. Akhurst is from the UK not Germany. The article in "Motorrad" also appeared in MotorCyclist or Rider in the US. Non the less, this is some fine engineering. Hip Hip Hurra to Mr. Akhurst.

Can a bit of extra mileage be worth the risk of blowing yourself up? Definitely not if you ask me. I'd much rather walk than ride an LPG powered bike!

If it was gasoline powered, I would love to have one.
