Alfa Romeo 4 Cylinder Boxer Powered Motorcycle

Alfa Romeo boxer powered motorcycle

Alfa Romeo engines must be a more popular transplant than I thought. Here's another motorcycle which looks quite finished and ready to ride. The engine is a 4 cylinder Alfa Romeo boxer but I can't tell you much else. The photos were taken in Belgium and there are a few notes by the images. As near as I can tell, the tank is from a Laverda, some bodywork is from a Yamaha 750 and the bike looks absolutely excellent.

Thanks for the tip, Mathieu!

  1. I never knew Alpha had an OHC flat four. Most likely never available in the US.

  3. That’s hott. I mean that in the best possible way. That looks like an Italian version of a cafe-racer late-’70s ‘Wing. Except sexier.

    But, uh, where’s the drivetrain? I don’t see a shaft, belt, or chain anywhere on that bike, unless maybe it’s hiding on the right side behind the exhaust.

  4. Nice use of an engine from an Alfa Sud. This is probably even cooler than the V6 powered one.

  5. This is DEFINITELY cooler than the V6. I think the drivetrain is hiding on the left side (facing as you would if you were riding) due to the drum brake’s position.

  6. It uses a BMW drive train (’60s transmission, ’70s rear drive), plainly visible.

  7. OK, actually looks like a ’70s BMW transmission but with a special adapter pate.

    Nice work. If I had the money, any money at all it would be mine.

  8. The bike has a Dutch license plate, so it’s Dutch (Luykgestel to be precise). It’s a home build motorcycle which was built in 1977. The comments by the pics at Flickr say the frontfork is from a 750 Yamaha. The transmission is from a 1977 BMW. The tank is from a Laverda, the chassis is lengthened, but I don’t know from which motorcycle the chassis originally came.

  9. Euro builders adapt that BMW driveline to alot of different motors, I’d like to know more about that, if anyone knows where there is any info on this. I have seen it adapted to a Harley Evo and a air-cooled VW.

  10. Outstanding! Looks like it could have been a factory bike, The transmission adapter plate is nicely radiused and blends-in well. This bike is rekindling the thought of a VW-powered bike..

  11. Casey, how about a WRX Subaru motor! Not that there is anything wrong with the excellent air cooled VW engine.

  15. Holy expletives! That Stiatv WRX quad would scare the intestines out of me.

  17. I saw this (or one like it) in 1980 in southern holland (Stein, Limburg) outside a chipshop. I remember I thought it was an MV, but the tank badge was an Alfa badge. My dad told me it was an Alfasud motor. The bevel drive is from a twinshock BMW. The one I saw was unfaired with a slightly more angular tank. One and the same??

  18. this engine was lifted from the alpha sud car produced in the late 70s and early 80s. it was an absolute craker of an engine whith a musical exhaust note. the car itself had superb handling caracteristics in typical alpha fashion
