The Triumph Street Twin will continue the success of the previous model. It does everything you want from a modern classic naked roadster, but now with improved braking, comfort, safety and more importantly performance.

The increase in power and more significantly the mid-range grunt has increased the appeal of the Street Twin and injected some excitement to the bike, whist still retaining its ease-of-use and rider-friendliness.

Major update in 2021

The biggest change for 2021 comes in the engine department where Triumph have managed the Holy Grail of a Euro5 update that also brings more power. This is achieved through lighter internal components resulting in a 17% reduction in inertia and the ability to rev higher. There is a new exhaust, too.

The result is a new peak power output of 98.6bhp @ 7250rpm and peak torque of 82.6lb.ft @ 4250rpm, plus you still get 10,000 miles before the first major service is due.

There was absolutely nothing wrong with the way the old bike handled, but Triumph are looking to build on this with upgrades to the chassis components, brakes and tyres.

Gone are the KYB forks in favour of higher spec Marzocchi units and the old bike’s axial Brembos are replaced with radial M50 calipers from the Italian supplier. The alloy wheels are now lighter, too, thanks to a new 12-spoke design and they come wrapped in brilliant Metzeler Racetec RR tyres.

As for the more subtle changes, Triumph say they’ve upgraded the riding modes but have stuck with the intuitive Rain, Road and Sport nomenclature. You also now get anodised headlight and mudguard mounts, brushed stainless, upswept exhausts and new tank graphics.

This bike replaced the 2016-2019 Triumph Street Twin. If you're after a bit more power and performance from your retro Triumph, you could also look at the speedier Street Scrambler.

There's loads of forums and online communities for the Street Twin. Once you've read this review and our owners' reviews, we'd recommend visiting the Triumph Owner's Motor Cycle Club for more.

The ‘entry-level’ Street Twin has improved handling and braking, with upgraded 41mm KYB cartridge forks and a new Brembo four piston caliper gripping a single floating disc, replacing the Nissin of old.

The huge Brembo caliper is not just eye-catching, but also delivers impressive braking performance, backed up by conventional ABS. The racing looking stopper is still user friendly and progressive, though.

The old 900cc machine was a little gutless, and could never have been described as exciting. However, that has been rectified thanks to an 18% increase in power - up from 54bhp to 64bhp. The upgraded engine revs quicker and to 500rpm higher, due to lighter internals. The result of this is a 2019 model that pulls stronger in the mid-range and feels more alive, underneath you.

Although peak torque is identical to the old model, there’s significantly more torque throughout the rev range, noticeable from 3500rpm onwards. Tap back one gear for a fast overtake and the new Street Twin delivers, whereas the old model was a little shy. A dealer fitted A2 licence kit is still available.

Reliability shouldn’t be a problem as the motor is based on the previous model with lighter internals and service intervals remain at 10,000 miles.

Our Triumph Street Twin owner reviews are very positive, with the exception of the standard tyres, which is often the case on new bikes.

The OTR price of the Triumph Street Twin has jumped up from £7300 in 2016 to a launch price of £8100 for the new 2019 model. That said, prices remain on par with the competition for the Hinkley designed Triumph, which is actually built in Thailand.

The Street Twin is a rival to the  reliable retro Kawasaki W800, suave Moto Guzzi V7 and British-designed Royal Enfield Continental GT.

Twin test: Triumph Street Twin takes on Yamaha XSR700

First published by Phil West, 27 March 2019

Triumph Street Twin vs Yamaha XSR700

On face value, the XSR is the better-value bike and the new Street Twin the more convincing retro; only it didn’t work out like that. The uprated Triumph is also, surprisingly, virtually the Yamaha’s performance match, is better equipped and, as expected, more charismatic and classy, too. Some of that is due to extras, so needs to be taken with a pinch of salt and there’s also no doubt the XSR remains a great-value motorcycle.

But while a couple of aspects of the Yam can be criticised the only ones of the Triumph that turn me off are its dinky size and cast wheels. And I’ve just realised that’s no problem, either. The equally new, 900-powered Street Scrambler sorts those issues out, too. So it looks like Triumph have got ‘classics’ covered.

Twin test: Triumph Street Twin vs Royal Enfield Interceptor 650

First published 2 October 2020 by Michael Neeves

Triumph Street Twin vs Royal Enfield Interceptor 650

In an effort to discover whether the 2019 Street Twin really is among the best in its class, we pit it against our Best Retro 2020 - the stunningly cheap yet capable Royal Enfield Interceptor 650. Here's our verdict:

Forget everything you know about old Royal Enfields because the new Interceptor 650 is in a different league. It still oozes old-school Enfield simplicity, but it’s well-built, classily finished and packed with well thought-out detail touches. It’s light, easy to ride, fun and handles incredibly well. At normal road speeds, it’s as capable as any retro roaster, but at a fraction of the price. Slicker, with funkier styling, more equipment, presence and more of a big bike feel, the Triumph is a class act and, compared to the BMWs and Ducatis of the world, decent value. It’s packed with character, superb handling, grunt, speed with easy road manners. It’s worth some of the extra cash over the Interceptor 650 for all its niceties, but for the pure riding experience there’s little to separate the two, which just goes to show what an incredible job Royal Enfield have done and why the 650 is our winner.


4 out of 5 (4/5)

For 2019, the Street Twin comes with class leading rider modes; 'rain' and 'road', which alter the ride-by-wire throttle map and traction control intervention accordingly. Both modes allow full power and can be changed on the move.

There’s a noticeable difference between the modes, with the rain mode significantly reducing the low to mid-range performance and giving the rear Pirelli Phantom an easier time in the tricky conditions we encountered; wet cobbles for example. Triumph have also installed an optional tyre pressure monitoring system, (TPMS).

Furthermore, Triumph have more than 140 accessories to personalise your Street Twin, and then there are countless aftermarket companies offering parts too.

Torquay, Punchy, light and easy to handle. ideal for town riding and haking round the Lanes. However motorway riding could probably could do with a sixth gear. The saddle hight is low and a comfortable riding position that is confidence inspiring. I am 6ft tall and find the bike comfortable on long rides. Best looking retro bike on the market and generates interest every time I ride it. I would defo recommend to a friend.

Very good allrounder with or without a pillion. single front disc is ok.

Engine 5 out of 5

Lots of low down grunt where you need it.

Reliability & build quality 5 out of 5

A sum of it's parts the bike is made from very high quality components, with the exception of flimsy indicators and Micky Mouse mirrors, aftermarket replacements are massively over priced.

Value vs rivals 4 out of 5

Good fuel economy, low insurance.

Equipment 5 out of 5

A simple bike, with few extras however the electronics are top draw.

Buying experience: I purchased the bike new from a dealer. I paid book price, but received a good PX on my old bike. The delivery was very late with no communication from the dealer.

Not the bike I wanted to buy, but as an average height person who wants to be able to simultaneously put both feet on the ground, the options are severely limited. Although brand new, the Triumph is a classic style so has a lower seat height. Unfortunately the luggage options are limited. The headlight needs to be much brighter on dipped.

Front brake was like an on/off switch till it had done a few hundred miles. My nuts were complaining after being pounded into the tank!I’m still adjusting the shocks to find the best settings.

Wow, lovely bit of engineering. Pulls right through the range, overtaking is a cinch.

It’s only a couple of months old so I’d be really miffed if it had broken down. It looks well built and sounds fantastic. It usually attracts an admiring audience as it has a special edition paint job.

Value vs rivals 4 out of 5

Too new to know yet.

Equipment 3 out of 5

Gadgets and modes are a bit thin on the ground. With a single speedo unit I miss having a rev counter. There is one in the small display but that has to be cycled through tyre pressures, clock, odometer, trips etc so not ideal. I’ve added a bar mounted clock which helps. Am currently adding SatNav for future trips.

Buying experience: Bought new. Unfortunately I was unable to try out a Tiger 900 low as they seem to be rarer than a competent Prime Minister! So once I decided to buy the Street Twin it all went reasonably smoothly.

Fantastic looking and quality machine. Easy to ride - just needs an extra 10hp and better engine braking to make it perfect.

Ride quality & brakes 4 out of 5

Why do comfort seats come as an option? Surely seats should be comfortable as standard.. this one is ok, but gets numb after about 50mins. Suspension is rear adjustable only, and gives a firm controlled ride. Tyres not the best in slippery conditions.

Engine 4 out of 5

Engine can struggle to keep up with mates.. just accept that fact and ride along to the smile-inducing exhaust note. Worst part is that for a big twin there's next to no engine braking.

Reliability & build quality 5 out of 5

Very reliable. Everything continues to work as it should. Been out on wet and muddy roads, but cleans up a treat. No visible rust or corrosion.

Value vs rivals 5 out of 5

Regularly get over 70mpg, and so far not had to top up the oil. Insurance cost very low considering it's 900cc.

Equipment 4 out of 5

Brembo brakes really good. Standard pipes sound as good as the V&H option. OE tyres aren't the best. Heated grips by far the most popular option.

Buying experience: Bought as brand new but in stock at end of quarter, so got good discount from dealer. Dealer also delivered it to my house FOC. Good experience indeed.

A separate tachometer would be more convenient. Lack of possibility to install rear spools. Really confortable on long ride (500 km) all day. Shifting is precise and smooth. Otherwise an excellent machine

Choice of tyres. Rear tyre is sometime at limit on wet pavement. Why not 2 radials?

Buying experience: Excellent service from my dealer
