Daytona 675 (D67LC)

Triple Character, Track Manners

The Machine's Character

Triumph's first real swing at the supersport class, and it landed by going its own way: a 675 cc inline-three instead of the inline-four orthodoxy everyone else built around. That triple makes 121 hp at 12,600 rpm with 54 lb-ft, but the headline number undersells it. The character lives lower down, where the three-cylinder pulls cleanly while the fours are still hunting for revs. Wrap that around an aluminum perimeter frame and fully adjustable suspension, and you get a bike that reads the road and goes exactly where you point it, with usable power most of the time instead of only at the ceiling.

On the road it carries that composure into real riding: settled through rough corners, suspension you can soften for a full day in the hills. This is a bike for the rider who values precision over brute output and wants genuine character without a temperamental machine underneath. The honest caveats are real too. Turn-in is willing rather than savage, throttle pickup off a closed corner sits a step behind the sharpest in the class, and the early regulator/rectifier carried a safety recall worth confirming on any used example. None of it dulls what this bike fundamentally is.

The Voice of Experience

Portrait of NastyNils

The test ride

Swing a leg over and the first thing that registers is how slim it is between your knees. Tall riders fit without folding up, and the bars fall right where your hands expect them. Wind the triple out and the intake takes on that distinctive three-cylinder wail, a sound the fours never make, with a smoothness through the pegs and bars that stays civil even up near the ceiling. The seat and riding position hold across a full day, not just a handful of hot laps. Run it hard for hours and nothing fades; the controls feel the same on the last lap as the first. Step off after a fast mountain run and you're relaxed rather than wrung out, hands and shoulders still fresh. Few bikes built this sharp leave you that composed at the end of the day.

Rated point by point — where it earns its keep

My own 0–100 score for this bike against the class, area by area — the marker on each bar is the class average.

What stays with me about the Daytona is how quiet it keeps itself when the surface turns ugly. The test circuit threw mid-corner bumps and broken asphalt at the edges, and the bike held its line through all of it, never going light or nervous on the way out of a bend. That matters more than it sounds, because it frees you up to think about the throttle instead of wrestling the chassis underneath you. It changes direction the same way it holds a line, willing and unforced, and it never feels like it's fighting a taller rider for room. The one honest mark against it is corner entry. Come off something that knifes to the apex on command and the Daytona feels measured by comparison; it tips in cleanly enough, but that first bite is calm rather than vicious. I'd take that trade every time for the composure it hands back everywhere else.

Point it at a real mountain road and the Daytona shows you everything it has. Hard on the gas out of a corner, the front skimming light over a blind crest as the next bend opens up, the surface rough underneath, and the bike simply stays organized through all of it. What sells me is doing that in company. A whole group of us ran that pace on bad asphalt without one heart-in-mouth moment between us. Not every sharp bike lets you trust it that far that fast.

The triple is the reason to own this bike. Wind it right out and the pull keeps coming well past where I expected it to sign off; the top of the range stretches further than the paper figure lets on, and it doesn't fall away in a hurry the way the older motor did. Down low and through the middle is where it truly separates itself, with a fatness of drive the four-cylinder bikes simply don't have until they're screaming. The practical upshot is laziness as a virtue. I could leave it in a tall gear through a whole sequence of bends and the motor never protested, never demanded a downshift just to keep pace. My only real gripe is the return to the gas after a closed throttle. Roll off for a corner and come back onto it, and the pickup lands a fraction late, right at the exit where I want it sharpest. A small thing on an engine this flexible, but it's there.

Here's the one trait that catches me out on an otherwise composed bike. Rather than fit a mechanical slipper clutch, Triumph cracks the throttle bodies open slightly under hard deceleration to soften the engine braking. Hard on the brakes in a straight line, it stays perfectly clean. Get hard on them while the bike is leaned over and the rear takes on a mild rhythm, a gentle shuffle that never builds into anything dangerous. On a machine this settled in every other situation, though, it's the one moment that reminds you it isn't flawless.

Two hard days gave me the answer here. The bikes ran in constant rotation on a punishing track, lap after lap with no cooldown, and neither the brakes nor the suspension gave anything away by the end. The asterisk is the rubber. The factory fits a genuine track compound and the grip is outstanding, but you pay for it in tread life. It vanishes far quicker than a normal sporting road tire, so ride it the way it wants to be ridden and you'll be shopping for fresh rubber sooner than you'd think.

This is where the adjustable suspension earns its keep away from the track. Wind the damping off and the bike feels like a different animal on the road; what was firm for hot laps turns genuinely supple. Riding out through town and up into the hills, the chassis soaked up the broken surface without punching anything sharp back at me, and the seating position never started to grind on me as the miles stacked up. For something built this focused, that kind of breadth is rare.

One thing to know if you like fiddling with settings on the move. Some rivals let you change instrument functions straight from the handlebar while you ride. The Daytona doesn't hand you that; if you want to alter a setting, you pull over and stop. It's a minor inconvenience rather than a real flaw, and on a bike this single-minded about going fast I rarely wished hard for it. Still, if you're used to managing things at speed, you'll notice it's missing.

The Truth on the Street

Known issues

  • Regulator/rectifier overheating and failure

    electricscommonRecall

    The regulator/rectifier can overheat, preventing charging and causing the motorcycle to stall. An NHTSA recall (12V445000) was issued covering 2006–2009 Daytona 675 models.

  • EXUP valve sticking

    exhaustoccasional

    The exhaust valve (EXUP) can seize or become noisy, triggering the check engine light and potentially affecting mid-range power. Often requires adjustment or replacement.

  • Oil leaks from engine bolts

    engineoccasional

    Some engines develop oil leaks from loose/broken bolts on the crankcase or covers after a few thousand miles, requiring re-torquing or thread locking.

Alternatives to the Triumph Daytona 675

If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.

Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Triumph Daytona 675. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
