Race replica hotshot that’s largely wasted on the learner market but goes like hell once derestricted without losing all of its economy (100mph, 60mpg). Extrema brings in all the goodies (and the expense) of the bigger stuff, including lack of comfort, and high price tag. Engines seem to last well for the first 25000 miles then have piston or gearbox hassles but there are some that have done more than 35000 miles. Pay attention to the electrics, frame and brakes.
