"It’s the 660’s ability to chill and thrill that makes it a rewarding companion. It can scamper through city traffic at 3,000 rpm, hold 70 mph at 6,000 rpm (in sixth gear) on the highway, or scream down the straight at 12,000 rpm. That versatility makes the engine a clear standout." Revzilla
"There’s something invigorating about a three-cylinder engine wailing at full song. The distinctive note accompanied by the rate of propulsion never fails to please, and the sentiment is yet again true with the Daytona 660. Get the engine spinning and it’s impossible not to smile." Motorcycle.com
"The engine and gearbox provide a lovely duet to your ride… the Daytona is part of the new breed of part sportbike, part street bike, part commuter, part whatever you like." Cycle News
"The tuning and how this engine responds is supreme… I think this motor shines against its competitors. You can just hear and feel this bike ready to go for you.. This exhaust sounds really, really good" Chase on Two Wheels
"...a streetable, sporty motorcycle that will give you a blast in the canyons, be comfortable enough to commute during the week, and more than hold its own during the odd track day or two, this thing is pretty rad. Good stuff Triumph, hell of a motorcycle." Motorcycle.com
