Street Triple R Low (HD04)

Reach the Tarmac, Not the Sky

The Machine's Character

The Street Triple R Low puts the 765 cc triple at a 30.7 in seat, so the rider who never quite trusted a taller middleweight gets the same machine on the same terms. Peak output is 116 hp at 12,000 rpm with 57 lb-ft at 9,400 rpm, running through a six-speed box with an up-and-down quickshifter and a slipper clutch as standard. Showa SFF-BP forks work the front, both ends are adjustable, and Triumph's ride-by-wire throttle maps sit behind the ABS, traction control and ride modes. Nothing in the package reads as a compromise trim built to hit a number.

On the road it does what a good naked should: light steering, a clear sense of what the front tire is doing, and enough lean clearance that the pegs stay out of the conversation on public pavement. It rewards a rider who likes to carry corner speed, and it stays civil at commuting pace. Aftermarket support is deep, which matters across the years you own it. The honest caveat: 4.6 gal and no cruise control make long interstate transits the weak part of the week, and heated grips, luggage, a USB port and tire pressure monitoring are all extras.

The Voice of Experience

Portrait of NastyNils

The test ride

The first few miles you notice how small it feels between your knees. The tank is narrow, the bars are wide enough to give leverage without stretching you forward, and at a stop both boots go flat on the pavement without any thought. The triple's voice sits between a twin's thump and a four's wail, and the note changes character noticeably as the revs climb through the middle of the dial. Vibration reaches the bars and pegs but stays as texture, never numbness. At 60 to 70 mph the wind pressure on your chest earns its keep: a legal pace feels busy and involving, which is cheaper than a ticket. Clutchless shifts land cleanly in both directions once you stop being polite with the lever. Two hours in, wrists and knees are still comfortable.

A winding asphalt road descending through the Appalachian Mountains, likely the famous Tail of the Dragon section in Tennessee and North Carolina. Multiple technical right-hand and left-hand curves are visible in this aerial perspective, surrounded by deciduous forest in spring foliage. Clear sunny conditions, well-maintained asphalt with yellow center lines marking the curves.

The Truth on the Street

Two decades of standing around with riders adds up. This isn't my own test notes but the collective read: talk at fuel stops and rallies, and the messages owners send once they've lived with a bike a while. On the Low the accounts line up neatly, with the enthusiasm and the criticism each pointing at the same handful of things.

Where The Praise Concentrates

The inline-three earns the most agreement. Riders describe a refined, linear delivery that stays docile in traffic and gets vocal and eager once the revs climb. Nearly as consistent is what they say about the chassis: the aluminum frame and adjustable Showa units get credit for precision and for the confidence that follows, with low weight mentioned in the same breath. Owners of this version mention the seat height mainly to say it takes nothing away.

The Gripes That Keep Repeating

Criticism stays narrow. Suspension is the main one: firm enough on good asphalt to be a virtue, harsh once the surface breaks up, and riders on the lighter end notice it soonest. Some blame the shorter travel of this version. After that it's the exposure at speed and a rear end short enough to throw dirt up your back on a wet ride.

Known issues

  • Missing Sport and Rider modes and auto-cancelling indicators on early models

    electrics occasional

    Some 2020 Street Triple R bikes were delivered without the advertised Sport and Rider modes, and auto-cancelling turn signals, due to a software/PDI issue. Owners report that neither dealer reflash nor Triumph USA has resolved it quickly.

The 'Should I Buy It?' Score

Forget spec-sheet bragging. Here's who the Street Triple R Low 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 motorcycle for Angeles Crest?

Angeles Crest suits this bike. It steers light, tells you what the front tire is doing, and runs out of lean angle long after you run out of road. The low seat just means clean, unwobbly starts from every turnout.

Best motorcycle for Tail of the Dragon?

For Dragon-style corner work, the flat-foot seat height and light steering let you spend your attention on line and throttle instead of managing the bike. The low-rev drive helps in the tight stuff.

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