Why These American Bikes Deserve Attention
These motorcycles show that American performance engineering goes well beyond traditional cruisers.
The potential of V-twin superbikes was investigated by the Harley-Davidson VR1000 and EBR models. Roehr experimented with supercharging, while Motus adopted a unique V4 strategy. MotoCzysz pursued unorthodox racing technology, while Lightning and Damon pushed electric performance.
Then there is MTT whose motorcycles with turbines appear to be in a class of their own.
However the finest bike is not solely determined by horsepower. The total experience is influenced by a number of factor including weight, chassis balance, brakes, tires, suspension, rider aids, dependability and parts availability. If a motorcycle’s handling and power delivery are more appropriate for the situation it may be quicker and simpler to ride on a tricky track while having a lower peak power.
A published power figure, a manufacturer’s claim, and independently measured performance are all very different. The motorcycles in this list come from different eras and use different powertrains, so the numbers should be treated as reported figures rather than a perfectly controlled comparison.
Final Thoughts
Japanese manufacturers remain major players in the sport-bike world but these American machines prove that there is more than one way to build a fast motorcycle.
Some rely on big V-twins, others use electric motors, and MTT has gone all the way to turbine power. Their histories are just as varied: some became rare collector bikes, some struggled to establish a market and others pushed the boundaries of what a motorcycle could be.
With a reputed 420 horsepower the MTT 420 RR is the star of the show. However rider that want unique engineering to large numbers could find the EBR 1190RS, Motus MST-R, and Lightning LS-218 as intriguing.
