Like many others here, I love the old board track racers, and while the replicas that many people make look beautiful, the engine never just looks right to me. Is there anywhere we can purchase low power singles and/or vtwins that look even somewhat like the old engines from the 'teens? I say low power, because we all know a 1000cc modern vtwin would tear a bicycle frame in half, yet the old 1913 indian racer had a 1000cc v twin that had less than 10 horsepower. Does anyone make a vintage looking, low power v twin or large single?
A better engine for a board track replica
- Thread starter metal
- Start date
I guess to say the obvious, I am planning on building a motorized bicycle, as similar to the board track racers as I can. If an appropriate engine is available for a reasonable price, I would like to build it properly (who wouldn't want a 1000cc v-twin on their bike?) However if an engine like this isn't available, then I'll just build it with a standard 49cc engine.

I have seen some large(like 100cc) motors for large scale R/C planes. I even think there is a v twin. I cant remember how cool it looks but you can check it out. Also you could find a honda v twin from somewhere like northern equipment and strip all the sheet metal off but its going to be pretty big. Sorry i cant help more but maybe it will get you in a better direction.
I've seen the v twin engines like the briggs and stratton and honda generator engines, but the only issue with them is that they're too wide. Height and length I'm fine with, I'll modify the frame so it fits, but too wide and I'll be banging my legs on it. Plus they're ugly, haha. The plane motors are a very realistic possibility, albeit sometimes on the pricey side (from what I've seen).
Another option I was thinking of was to just use the engine/tranny from an old 70's motorcycle, something like a honda CB125. While definitely more powerful than the 49cc singles most often used, I think that 125 is low power enough that I could make it work safely in a bike frame with some reinforcement, thick spokes, and good brakes.

You know, the more I look at them, the more I think the 2 stroke, 49cc engines we use are **** near perfect, just too small. More specifically, too short. If there was one that was similar to the same size as the current little ones (maybe a touch larger in the crankcase area) but had a cylinder that was a good 2-3 inches longer, that would be a perfect look. I imagine that doesn't exist though haha.
Like Lifan engines ??
Her is a link to those & others.

Wow, did you guys see that 250cc v twin?
I've seen the lifan v twin, and I'd love to build something around that, but I was hoping for something more... vintage looking. The jugs on the old v twins in board trackers look like a pipe with some fins brazed on (who knows, maybe they are). Does anyone make old replica v twins?
Something that looks more like these engines

You can buy model V-Twin but they cost way to much $$$$$$$$$
The one that i would buy if i had money and IF the person that build it made more would be the one in the picture(v-twin) but i also found one that you can by plans but looks to small and not as good(i dont like the cover with the fans on the top of it)
AND IF YOU LIKE BIG THINGS GET THE V-8 FLATHEAD
