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.

Overall, the Bonneville T100 is far more than simply a retro-styled Street Twin. It is a bike that has all the relaxed nature and beautiful look of the larger T120, but placed a smaller, lighter and arguably more fun and engaging package. Fans of the previous Bonnie will love it and I’d urge riders looking at the T120 to also take the T100 out for a blast, you may well find it more to your liking.

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.

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 new SV.

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.

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.


5 out of 5 (5/5)

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.

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.

Ride quality & brakes 4 out of 5

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.

Engine 5 out of 5

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.

Brakes fade if you start pushing the engine, also the ride is a little uncomfortable for a pillion but it's ok solo.

Beautiful little Bonnie. Would have given a 5, but just a fraction underpowered.

Ride quality & brakes 5 out of 5

Smooth, easy going comfort.

A tad more power would improve.

Still running-in...but so far so good.

Value vs rivals 4 out of 5

Fuel consumption looking great so far

Equipment 5 out of 5

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.
