Benelli BX449

[JR @ CFS]

Just got my hands on the latest MCN and saw a new motox bike called a BX449. Engine is a single, 52bhp at 10,000 and 32ftlb of torque. Sounds interesting. I'd say it would be nigh on impossible to get your hands on one...it seems they aren't in full scale production just yet.

Suprised that being from sweden you arent promoting the use of Jawa Speedway engines. I talked with them alot and using either gas or alcohol with a homemade blower fan for the fins it would hold up just fine. No cooling system weight/packaging to worry about and they are perfect for mounting. Oh yeah. Gotta use a cvt or separated gearbox but they holds many adavantages since you can lay these things down flat. Just a thought.

Well, although my profile says "Goteborg, Sweden" I originally hail from Ireland. Not much to root about there except for the Titanic and DeLorean! Both catastrophic failures and famous for all the wrong reasons http://fsae.com/groupee_common/emoticons/icon_wink.gif

I know that Lund university did use a sidecar or possibly a speedway engine this year and they had nothing but problems with it, especially when it came to spares. That's the problem with moving into specialty engines, getting spares is a nightmare. Ask any team who ventured into Mahle territory!

I would be interested to find out more about that. Site or pics of that thing.

Rob,

The engine we used was based off a sidecar/motorbike engine block by a company called folan, www.folan.se (http://www.folan.se) who have done alot of prototype work for husaberg and huskvarna iirc.

The engine we used is currently in production for highland motorcycles, www.highland.se (http://www.highland.se) and also used by a few cross/sidecar racers.

It is basically too large displacement for FSAE, whilst still beeing quite a bit lighter than a f4i. So what we did was increase the displacement even more with cylinders from an industrial unit (from 950 to 1150) and mount a self designed/manufactured head on one cylinder, making it act as a two-stroke piston compressor supercharging the other cylinder.
