A perfect example of this comes from the updated Trident 660 and Tiger Sport 660 which feature a heavily revised 660cc Triple that completely transforms the riding experience. The big headline? A massive 14-horsepower leap, pushing peak output up to 94 horses alongside a punchy 50 lb-ft of torque.If you've read the First Ride reviews of both bikes, you'll know the engine performance is the saving grace for both models, as their chassis and brakes were a little bit of a letdown in the twisty stuff.

Of course, we love twisting the grip on that Triple because it unleashes that iconic exhaust note we can't get enough of.So, where did all that extra grunt come from?
