We expect it is doubtless that there are a number of car or motorbike fans — some could also be studying this proper now, in reality — who’re all the time dreaming of what they’d construct if solely they’d the time, abilities and cash required for such a mission. And we get it; most of us who write about automobiles for a dwelling fall into the identical camp. However there are additionally a really choose few who determine to cease dreaming and get away the instruments. Marek Foltis belongs in that latter group.
We have exchanges just a few emails with Marek, and earlier than we go into the small print of his unimaginable Bistella 500 motorbike, it is useful to grasp what may possess an individual to set about with such a monumental activity. “Truthfully, I do not know what sort of satan possessed me,” he informed us earlier than breaking his actual motivation into two elements. He stated he had been “tinkering with motorbikes for 15 years” and puzzled “what I ought to do to check the bounds of my means.”
By setting a bar increased than the set of abilities he had when he began ensured that he would fail. And that was the complete level. “With failure comes expertise,” Marek defined to us, and “with expertise your means rises increased. So I knew that I’ll fail rather a lot. I knew it even earlier than I began. So I wasn’t stunned when it occurred … each time I failed I knew that was crucial to realize slightly bit of additional expertise. So it didn’t price me emotional drain, that is how I bought persistence wanted.”
In a extra matter-of-fact secondary reply to our seminal query, Marek informed us he wished to construct one thing that would actually be one among a form. He set out with a transparent set of parameters: It should be road-legal, it needed to be constructed utilizing elements made by Jawa however with an engine of his personal design, it will be impressed by ’50s and ’60s bikes however invoke a sure shock-and-awe sort of response and be free from too many trendy gadgetry.
As a result of Jawa solely made two-stroke engines, Marek’s bike could be two-stroke too. His need to be distinctive led him to design a one-off radial two-stroke with integral superchargers. He settled on 10 cylinders as a result of 8 would have been tougher along with his crank design and 12 would not match into the exceedingly small Jawa body he used for his machine.
Lest you assume that is nothing greater than a museum piece, here is video proof that it runs and that Marek, the builder, rides it. As you’ll be able to see, the outsized engine is a good match into the little Jawa body, however all the things sits proper the place it is presupposed to and appears superb.
Not that the method of turning the Bistella dream into actuality wasn’t with out incident. “I blew the engine 5 occasions,” Marek informed us. “Protecting my thoughts optimistic was the toughest, I used to be undecided if this idea will work,” he stated. “I wasn’t positive it should work till the primary begin.”
However begin it did. In its present type, Marek explains that the Bistella 500 produces a comparatively low 12 horsepower, however that is simply because he needed to tune it that method to get it street authorized. “EU paperwork is so inflexible,” Marek defined to us. “I needed to undergo a number of security inspections, assessments, and homologation it took me a yr of stamp searching. However lastly, it is authorized and insured.”
Marek calculates that the Bistella’s 10-cylinder supercharged radial two-stroke engine can spin out 120 horsepower when totally uncorked, although it is arrange for a restricted 60-horsepower tune in non-road-legal guise. Irrespective of its state of tune, although, it sounds superior, as you’ll be able to hear within the video up above.
What’s subsequent for Marek? He tells us he is contemplating just a few choices, one among which is a rotary radial the place the cylinders spin round a stationary crankshaft. Sounds loopy, however we would not put something previous him. And he would not put something previous you, both. “Anybody could make this stuff occur,” he says, crediting his persistence as a substitute of his intelligence or training for the Bistella 500’s success.
“I am satisfied that there are literally thousands of tasks like this in garages ready to be executed, and the one lacking half is encouragement,” says Marek. “That’s the message I’d like to convey with this mission.”
Take into account that message despatched, Marek. And congratulations on a really spectacular construct.
