Fresh spy photos of what’s purported to be an all-new liquid-cooled Triumph Bonneville for 2016 have just surfaced from across the pond. They reveal a new engine, new chassis and new styling that’s even more authentically retro than the current model.

Though the new engine appears to retain fully-functional cooling fins, there’s also a radiator mounted just behind the front wheel. Coolant hoses, though, are nowhere to be seen, suggesting the new bike might route coolant through its frame tubes. Our source informs us there’s no visible water pump, either, which means Triumph may be using an electric pump a la Harley-Davidson’s ‘Project Rushmore’ bikes.

Dual-disc front brakes are a bit of a surprise, as previous spy photos revealed only a single-disc setup.

There’s also a catalytic converter underneath the front of the engine the headers feed into, cleverly concealed by covers that give the impression it’s business as usual all the way from exhaust ports to peashooters. At the other end of the engine, the Bonneville retains fuel-injection throttle bodies disguised as old-fashioned carburetors.

The engine cases and covers closely mimic those of the unit-construction Bonnevilles of the 1960s, instead of the current model’s pre-unit Bonneville looks. U.K. government databases say the new bike is registered as having the same 865cc capacity as the current model, but inside sources have suggested that the new engine is somewhat larger in displacement. Either way, the addition of liquid-cooling hints at a significant jump in performance.

Bigger, sportier tires back up that suggestion; this prototype rolls on a 150/70 R17 Pirelli Phantom SportsComp at the rear – up from a 130/70 on the current bike. And the front wheel is 18-inches in diameter instead of 19, with a 100/90 R18 tire. Wire wheels hint this is the T100, since the current line-up puts cast alloy wheels on the base model. The speed sensor rings of the ABS brakes, a legal requirement on new bikes over 125cc sold in Europe from the start of 2016, are glaringly obvious. Maybe the finished product will hide them like Harley does on a bunch of its “retro” bikes?

The Bonneville and its variants are a critical platform for Triumph, so we’re anxious to see this new version in its final form. Expect full details at Italy’s EICMA show this fall.

    I for one and excited to see what his new engine has in store. I have been wanting to add a speedmaster to my stable for awhile.

  • 2wheelsgood

    Looking good, more and more like a Kawasaki W650 every day. Oops, I meant an original Bonneville.

  • martin collins

    No matter what it ends up looking like, a water cooled Bonnie is not a good idea. Triumph risk losing that heritage claim with this model. The current air cooled unit can easily handle more power. Maybe it’s an emissions thing, not sure, but I won’t be trading in my Bonnie for this piece of tat.

    • Bmwclay

      If Harley Big Twins could pull it off, so can the Triumph Bonnie.

  • JWaller

    Twin disks up front is a good change too. Though one of the most enjoyable aspects of the bonneville line-up is their simplicity. Oh well, progress.

  • Ducati Kid

    Hinckleys major concern?
    Offending existing and prospective clientele with lackluster TRIUMPH ‘branded’ motorcycles.
    From what I view precisely that, nothing new, ever distancing themselves from an innovative past that keeps facilities and dealer doors open.
    ‘Earn from enhancing your Past’ or suffer the consequences!
    Example: Brake replacement, other than Rotor Disc’s can be done employing – INNOVATION …

    • JWaller

      I seem to remember when the Daytona 675 first came out, how innovative it was then. Now other companies are making triple supersports of about the same displacement.

      • Ducati Kid



        This ‘base’ engine has been expanded to 800cc powering Hinckley’s ‘Tiger’ Series of motorcycles.

        Love the ‘Howl’ these Triple’s make!

        The Marketing advantage for Triumph?

        Hinckley manufactured!

        Technical Innovation –

        Believed by today someone at Hinckley would have devised a Rotor Cover with integrated L/C (Spray) hardware Single Disk revision for all ‘Bonneville’ models as Meriden (pre-70’s) employed Conical brakes.

        Reasoning, this design is widely used in Production and Saloon Automobile Racing where it works well cooling Disk Brakes.

        Motorcycling use?

        Enhanced performance AND looks!

  • Brent Randolph

    Ugh! Still with the fake carb?! It is a black mark on what is otherwise a fantastic bike and has been every since the bike first went to EFI. For the love of everything good and wholesome in the world, Triumph, dump the carb in the final production model. Retro styling is fine. Manufacturing a fake carburetor with a fake enriching knob to cover up the EFI because “it looks older” is not fine.

  • Craig Freger

    Finally! That awkward kink in the midpipe is gone! This actually looks better than the current Bonnie, even with the radiator.

  • Luke

    I wish there was some obvious “weight savings” going on here. That’s always been the weak spot on this bike for me. I don’t mind it not having 80hp, but the weight ruined it for me.

  • disqus_9GQw44dyM0

    Yep the kink is gone…but how about losing at least 50lbs as well. And no additional seat height!

  • JMDonald

    I will reserve judgement until a full production model is released. I like the two disc front wheel.

  • Jeff Keene

    To each their own and all that but frankly the whole retro thing doesn’t really appeal to me. I can’t help but feel like motorcycle manufacturers could be doing so much more cool stuff if they were not trying to make baby boomers feel young again. What’s that? Baby boomers buy a lot of bikes? Alright, well, fair point. But I was much more interested in the new Tiger 800 than I will ever be in a new Bonnie.

    • Kenneth

      “…manufacturers could be doing so much more cool stuff if they were not trying to make baby boomers feel young again” — Really? If you’re more interested in a new Tiger 800, who’s stopping you? There’s an amazing range of products for everyone (or, did you just want to rant here about “retro?”).

    • stephanie croc

      but that’s why they’re soft and unthreatening. Baby Boomers have earned the right to have more than just H-D as offerings, haven’t they?

    • ELGuapo

      Lots of young people love the old school bikes, Bonnies Harleys etc.
      Timeless design.
      The new Tigers look retarded. Probably great bikes though.

  • oldrepo56

    Water cooled , just one more thing to go wrong. I prefer the KISS theory. Keep it simple,stupid.

    • Sentinel

      When was the last time you heard of a liquid cooled motorcycle engine “going wrong”? lol

      • TonyCarlos

        I’ve replaced more than one water pump on bikes. And at least one radiator that ate it’s cooling fan.

        • Sentinel

          Which bikes were they?

          • TonyCarlos


          • rudedog4

            ach, ze Germans…

          • Sentinel

            That explains it then.

          • TonyCarlos

            Right, because there have never been heat-related issues with WC Japanese bikes.

  • It’s ticking all the boxes for me. When this comes out, I’ll be taking a serious look at it.

    • Sentinel

      Stop the “Obsession” now! lol

  • rudedog4

    get rid of bloody screws holding the seat on, hinge it on one side with a lock keyed to the ignition key on the other side.

    • Reginald Pettifogger

      Yeah, something like the old 350 Speed Twin from the Late-50’s would be nice, less the bodywork (or not).

  • blansky

    Call me old school but I sort of like leaving the 60s in the 60s.

    • stephanie croc

      I hear ya. I came back to riding with a 2001 Bonneville. Couldn’t learn to love it even though I loved the idea of it. Moved on to modernity within 8 months

  • vitor

    Fuck this bike.

  • frankfan42

    Is it possible the new “Radiator” is a huge oil cooler?

    Triumph bonneville – Time is limit, Passion is whole life

  • ELGuapo

    I probably wont ever buy a bike Ass-sembled in Thailand

  • rurhrurh

    Could it BE any more boring? (answer hint: NO). Triumph continues cornering the market in the fine art of Standing Dead Still…
