Far more than simply a retro-styled Street Twin, the Triumph Bonneville T100 has all the relaxed nature of the larger T120, but in a smaller, lighter and arguably more fun and engaging package. Fans of the previous Bonnie will love it.

Triumph describe the T100 as far closer in character and feel to the T120 than the Street Twin. This bike is, essentially, a smaller capacity T120 that is not only £1500 cheaper than the 1200, it is also 11kg lighter, easier to manage at low speed and yet just as handsome.

Yet, and here is the real killer point, it handles, stops and goes like the Street Twin. This may upset a few people, but after riding the T120 and then a Street Twin, I actually enjoyed the Street Twin more. The larger capacity bike is excellent, but its low-revving engine is relaxed to the point of being lethargic. In comparison the Street Twin’s 900cc motor brought a pleasing amount of poke and a free-revving spirit.

If I took pillions a lot or was after gentle hassle free riding then I totally understand the character of the T120, but for solo blasts it isn’t that thrilling compared to the smaller machine. This is why I was looking forward so much to riding the T100, if Triumph nailed the T120’s styling and successfully blended it into the Street Twin’s fantastic basic platform it would be a winner.

You don’t need me to tell you the T100 looks smart. With its peashooter exhausts, wire wheels, long mudguards and two-tone tank it brings every bit of T120 quality with it. For fans of the traditional Bonnie styling it ticks every box and for riders like myself who want a bit of modern handling and performance it doesn’t disappoint...

During 2015 MCN's Simon Relph spent a year living with the Bonnie T100. He said "It’s not particularly fast, it’s definitely not light and it’s not the best handling bike in the world, but what it lacks in these areas it gains in character". Read more here

The T100 feels very light at low speed yet turns and holds a line through a bend with more agility than the larger T120. It’s not quite as sprightly as the Street Twin due to its longer forks, and does lack ground clearance as its pegs are set for comfort, but thanks to better suspension and tyres it easily tops the older air-cooled Bonnie when it comes to enjoying corners.

The riding position is far more ‘traditional’ in its stance when compared to the Street Twin and the pegs are set low with the bars wide and flat, which is exactly what you would expect of such a model. It feels correct and is pleasingly relaxed and spacious when compared to the more compact Street Twin thanks to its larger seat and T120 riding position.

Yet it does all this and manages to retain the Twin’s improved handling. I found the T120 model’s front end a bit sluggish to turn, but despite the T100 sharing its chassis and having the same 18-inch diameter front wheel, the reduction in weight has taken most of this feeling away.

Like the previous small capacity Bonnie, the T100 comes with only a single front disc and two-piston sliding caliper. While this set-up still requires a good old tug on the lever, the fact it now incorporates ABS makes its slight lack of feel largely irrelevant. On the older model you never had this reassurance and the lack of ABS meant you couldn’t just grab a handful, especially if the road was wet. Now, thanks to modern electronics, you can.

During our Triumph Bonneville T100 long-term test, we swapped the rear shocks out for a pair of Progressive Suspension items. Find out how we got on here.

The water-cooled parallel twin motor still thumps along like an air-cooled unit should but is smoother than before with a pleasing mid-range and even a bit of a top end zip, yet working behind the surface is traction control. The clutch is nice and light and there is even a neat ‘anti-stall’ rev rise much like Suzuki has incorporated in the 2016 SV650.

This may upset a few people, but after riding the T120 and then a Street Twin, I actually enjoyed the Street Twin more. The larger capacity bike is excellent, but its low-revving engine is relaxed to the point of being lethargic. In comparison the Street Twin’s 900cc motor brought a pleasing amount of poke and a free-revving spirit. If I took pillions a lot or was after gentle hassle free riding then I totally understand the character of the T120, but for solo blasts it isn’t that thrilling compared to the smaller machine

Triumph has lavished care and attention to detail on the T100 and it looks fabulous. The small touches such as the hand painted coach lines on the tank and chrome engine details really set it aside from the competition.

Our Triumph Bonneville T100 owners' reviews show relatively positive results. The main comments are around the somewhat unsophisticated suspension, which is something buyers often upgrade. 

In March 2019 a recall was issued for the T100 alongside several other Triumph models for a wiring issue. Read more here.

At £8300 (or £8600 for the two-tone paint option) the T100 is very good value for money and bang on the mark in comparison to its competition. The T100 Black, which is £8300, covers the chrome details with matt black paint.

Rivals are the Royal Enfield Interceptor 650, Kawasaki W800 and BMW's R nineT.

It may not look modern, but the T100 comes loaded with traction control, ABS, ride-by-wire, an immobilisor and even a USB slot hidden under the seat. Cruise control and heated grips are optional extras.

In November 2019 Triumph announced the Bonneville T100 Bud Ekins to celebrate the hollywood stuntman and off-road racer.

5 out of 5 Classic black beauty.

Version: black

Year: 2019

Great sounding classic style motorcycle, the black paint scheme really sets it off with just small touches of chrome. Overall the bike handles well and feels secure even in the wet. Seat comfort is good, and the height of 790 was just right for me with my 5 ft 9 height, the flat seat is also welcome as previous bikes with there raised rear sections tended to catch on my boots when attempting to get on a bike.Only one small annoyance, the gear indicator which is set in one of the clocks, is too small to read especially at night, although only having 5 gears its not really an issue, but a sixth gear would be nice like the 1200 Bonneville. Finally, a main stand fitted as standard would be a welcome touch, instead of paying out over £150 + for one

Ride quality & brakes 4 out of 5

The bike is at its best between 40 and 70 mph, the revs as non intrusive to the ears or handlebars, and returns a very respectable 65 plus mpg. However although the seat is comfortable for around 2 hours or so, eventually areas of you do start to require a break.Brakes are OK, although a twin disc set up on the front ( like the 1200 has) would be more confidence inspiring.

Engine 4 out of 5

With a top rpm of 6k, this is not a racing machine by any means, but the twin does produce usable low down torque, and will pull away from traffic lights etc, with confidence. Running to the red line in most gears is not what this bike was designed to do, although will, but beyond 5500 revs, the bike tends to start to become pointless in doing this.

Reliability & build quality 5 out of 5

Build quality is excellent, currently no issues with reliability and Triumph have a great after market of accessories available for you to add your own mark to the machine, however they are not the cheapest on the after sales market.

Value vs rivals 5 out of 5

My Bonneville was recently purchased from Triumph Essex, as an ex demo machine with 300 miles on the clock, so was given a service before hand over to me, but as the bike does not have a large amount of fairings ( In fact none) to be removed, and everything is easily to hand, servicing cost should be acceptable.

Equipment 4 out of 5

My favorite features of the bike, are ease of handling, great original tyres which give confidence in the wet.Fitted crash bars to protect against dropping the bike, what with the bikes exposed crank cases and exhausts, fitted non Triumph make for £120. Finally, the bike does need a center stand and it would be nice for Triumph to make it a standard part .

Buying experience: Purchased from Lings Essex Triumph , having PX my Kawasaki w800 against it, very pleased with the dealership, the salesman was polite and professional in the way he arranged a test ride and made time to talk to me about the bike .Bike originally registered in Dec 2019, but due to the lock down ( Covid) the dealership was reduced in opening hours and test rides until June / July, therefore the bike mainly sat in the show room , hence the low mileage when i purchased it. Price paid £ 7700. The dealer even carried out the first years service ( Free) and presented me with a genuine Triumph back pack to carry my paperwork home in, these retail at just over £80, well pleased!

Looks fantastic, plenty of performance and a fabulous feel good factor on the road. Absolutely stonking bike to own and ride and I would recommend the T100 very highly.

Suspension fairly basic but handling is excellent and comfort is pretty good all things considered.

Engine 5 out of 5

Some may find 54 bhp a little tame but still plenty for real world riding and keeping your licence intact!

Reliability & build quality 5 out of 5

Only 7000 miles on it so far but hasn't missed a beat or given a millisecond of concern about reliability. Build quality is also excellent in all areas.

Value vs rivals 4 out of 5

Easy for the home mechanic to service and I do all of my own servicing. Parts prices not too bad not expensive to keep on the road. Haynes manual and 'Dealertool' software worth every penny. 'Dealertool' software enables the user to do all the diagnostic checks and bleed the ABS saving a packet compared to dealer prices.

Equipment 4 out of 5

Shame the centre stand is a £300 option and not standard and it needs the (£160) grab rail so you can get it on the stand without pulling the seat off. I like the range of accessories to smarten the appearance.

Buying experience: Bought second hand from Triumph dealer and service was excellent.

Superb for just the pleasure of riding and enjoying the little and curvy roads around Lisbon.

Ride quality & brakes 5 out of 5

Using the bike for what it is designed it is a tremendous pleasure. Position is comfortable, even in +3hr rides and brakes have enough braking power if you don't go nuts.

Engine 5 out of 5

Lots of low torque and great entry and exit at curves.

Reliability & build quality 4 out of 5

Not a problem in the last 12 months and 12,000kms just one bolt got rust which is not great.

Equipment 4 out of 5

It is a modern bike and it has all it needs for pleasure rides, but maybe cruise control would have been welcome for some longer rides that require 1hr plus on a highway.... I have crossed from the most western part of Portugal to the most eastern part of Spain and in secondary roads it is marvellous but highways get tiring on the neck and annoying not have cruise control.

Buying experience: Bought from Triumph Lisbon and quality of service was OK.

This is a beautiful bike that’s a joy to ride around town. It is super reliable, confidence-inspiring and easy to ride. It's also a constant conversation-starter wherever I go. Out of town on open highways a sixth gear would be nice, though.

Rear suspension gets overwhelmed by larger pavement imperfections. Avoid those little divots and cracks in the asphalt if possible.

I love it. This is no superbike, but the torquey motor has scads of usable power from idle to the redline.

There is no centre stand, which I would consider almost essential. (I bought and installed one from the dealership.) There is also no helmet lock, which is an ever-present irritant.

Buying experience: The buying experience from Blackfoot Motosports was excellent.

Had the fox shocks fitted as a triumph 'deal' (seem fine but nothing to compare them with)

Buying experience: Webbs, Peterborough made it a simple part exchange deal.
