Every bike needs a bang, but how you go about making an engine makes all the difference.
1. Inline Four
If you're after good, honest power - and are on a bit of a budget - then look no further than the inline four. This simple configuration has been producing proper power for years, and does the go-to option for those want an effective solution, the small cylinders producing efficient kinetic energy. It may not be the smallest or the smoothest, but the revs rise the advantages are obvious.
2. V-Twin
The benefits of the V-twin setup are clear. V-twin motors are inherently compact and slim, allowing engineers more leeway to design their chassis, not to mention they’re capable of producing massive shove, Depending on the v-angle, the characteristics of the motor can change, but while dirty big pistons may prevent dizzying redlines and massive speed, what they offer through midrange makes up for it.
3. V-Four
The lovers choice? Blending the compact solution of the V-twin and the strength numbers of the four, a V-four is an elegant solution to create power – at a high price. Some elements cancel each other out, like a short crankshaft then requiring two pop ends, but thanks to a more regular firing order, the creamy smooth delivery means a refined ride all the way to a madness top end.
4. Inline Triple
If we were talking about Benellis, the Foggy Petronas effort or ill-fated Aprillia cube engine, then perhaps the praise for the triple wouldn’t be as glowing. But thanks to Triumph, the triple is back in vogue – proved by MV’s release of its F3.
5. Single
The humble and maniac engine of the two-wheeled world. It’s advantages boil down to one massive plus- cost. KTM may be pushing the boundaries of engine dynamics with the Duke 690, most singles are simpler, smaller and considerably cheaper.
6. Flat Twin
The flat twin, aka Boxer, has been the mainstay for BMW foe generations. Why, I’m not sure, because they have inherent disadvantages, like a lack of balance and the top ends exposed to crash damage.
7. Straight Six
A V6 has the potential to rev harder and produce more power, but a straight six is simpler – and almost as smooth. Weight and width issues are the only setbacks.
8. V-Five
Included solely because of the RC211 V’s sheer brilliance, the V5 can use smaller pistons and still have the same capacity. So can rev higher and produce more peak power – for minimal area losses.
9. Parallel Twin
Half an inline four, the parallel is a cheap and cheerful answer when you’re looking for the next step up from single. Crankshaft configurations can vary but balancer shafts are required to curb vibrations.
10. Rotary
The Wankel engine has failed to set the world on fire. It does what four strokes do with a three-sided symmetric rotor rotating within the cylinder housing. Its clever, light, simple and powerful, but struggle with economy, emissions and longevity issues.
