Austria's Purist British Twin

The Machine's Character

The Newchurch is a special edition of the air-cooled Bonneville, built to mark the Tridays gathering in Austria, and Triumph put its effort into how the bike looks rather than into the spec sheet. Underneath sits the 865 cc parallel twin with its 360-degree crank, making 67 hp and 50 lb-ft, fed by fuel injection and cooled by the air moving across its fins. A steel double cradle frame carries all of it. No ride modes, no traction control, no screen to scroll through. It sits at the purist end of the modern classic field and makes no apology for that.

It rides the way it looks. The torque does the work, so you short-shift and let it lope instead of chasing revs. Ownership stays straightforward: 40 mpg, five gears and a chain to look after, low running costs, a dependable air-cooled twin, and an aftermarket deep enough that no two of these stay identical for long. It fits the rider who wants presence and calm on back roads, in small towns and on weekend trips. The honest caveat is what it goes without. No ABS, no traction control, and 496 lb (225 kg) to steer puts wet roads and heavy traffic squarely on you.

Chassis

  • Rear Suspension Adjustable Standard
An elevated view of a deep autumn canyon, likely Big Cottonwood Canyon, Utah. Steep rocky cliff faces and forested mountain ridges frame a narrow valley where a winding two-lane road passes below. Deciduous trees display full autumn color — gold, orange, and amber — interspersed with green conifers on the steep slopes. A single dark vehicle is visible far below on the road. Snow-dusted mountain peaks rise in the background under a partly cloudy sky.

The Truth on the Street

None of this is my own test ride. It's what has filtered back over years of listening to owners at rallies and club nights, in paddock talk, and in the messages riders send me directly. For the Newchurch the pattern holds steady: praise is about character and easy ownership, complaints about running gear.

Old Look, No Old-Bike Hassle

The loudest agreement is on the look. Owners describe paint and finish that read like the British twins of the sixties, not a modern bike playing dress-up. Riders also keep saying how little the thing asks of them: it starts, it runs, and servicing stays basic in a way restored vintage machinery never manages. Slow-speed manners get steady credit, with wide bars and balanced weight turning U-turns and tight parking into non-events. A smaller group brings up resale, saying these hold their money better than the competition.

The Brake And The Bumps

The front brake comes up more than anything else. Riders say it wants a hard squeeze and gives little bite when you first touch it, and it shows up fastest two-up or when the pace picks up. The suspension draws the other recurring note: on broken pavement owners describe a short, choppy ride with sharp edges coming straight through.

Known issues

  • Premature electrical sensor failures

    electrics occasional

    Throttle position sensors, coil packs, and camshaft position sensors can fail on older or high-mileage examples, causing rough running or no-start conditions. More common on earlier carbureted or high-mileage bikes, but certain models are not immune.

  • Corrosion on fasteners and brightwork

    bodywork occasional

    Bolts, engine covers, and chrome plating can show rust spots if the bike is ridden in wet weather or not cleaned regularly. This is primarily a cosmetic concern but may affect resale value.

The 'Should I Buy It?' Score

Forget spec-sheet bragging. Here's who the Bonneville Newchurch is actually built for.

A scenic view of Angeles Crest Highway winding through rugged Southern California canyon terrain. Rocky mountainsides with golden earth tones frame the asphalt road with tight sweeping curves. Double yellow center line visible, sparse vegetation along the shoulders, clear blue sky with white clouds. Daylight, dry conditions. Iconic location for canyon-road enthusiasts.

Best retro motorcycle for road trips?

This one is built for you. It looks right parked outside a diner, it is happy holding a two-lane pace all day, and 40 mpg keeps the fuel stops predictable. Pack rain gear and plan your own throttle work.

Best cruiser for Sturgis?

You get the look, the beat and conversations at every gas stop. Just know this is a lean British twin, not a big-bore highway cruiser, with no luggage and no cruise control for long interstate runs.

Best motorcycle for Texas Hill Country?

Fine for a relaxed loop with a lunch stop, less convincing when you want to push. It runs out of appetite as the pace climbs, and there is no ABS backing you up on unfamiliar pavement.
