It’s ironic, but in making the RS such brilliant value for money, Triumph have done the S model a disservice. The S is a great naked roadster motorbike that has a wonderful triple motor and a good level of equipment.

But, and it is a big but, the Triumph Speed Triple 1050 RS is priced so tantalisingly within reach for an incredible amount of extra equipment, it’s almost impossible to turn it down – especially as most of the items are inevitably bought aftermarket by owners anyway. If you owned a Speed Triple S you would be delighted, right up until the moment you parked it next to an RS, at which point your heart would sink slightly.

Triumph finally gave the Triumph Speed Triple RS a proper overhaul to bring it up-to-date with the super naked motorbike competition in 2023 with the Triumph Speed Triple 120 RS.

The S rides beautifully on the road and you never call into doubt the quality of the Showa suspension or that beautiful triple motor. It’s just a wonderfully good fun bike to ride and while not as full-on as other super nakeds in terms of performance, that’s not its target audience. This is a bike to be enjoyed – and thanks to that triple motor with its new lease of life, you will certainly enjoy riding the Speed Triple S.

The 1050cc triple has received, according to Triumph, over 105 new parts for 2018 that has boosted its power by 10bhp and torque by 4ftlb. It’s a wonderful motor that sounds deeper and responds faster than the previous generation’s engine. As a relaxed road bike it’s perfect and has enough grunt to deliver thrills without too many spills while the gearbox is positive and precise – unlike on so many of the previous models.

The build quality appears very impressive on the Speed Triple S and anyway, if it all goes wrong Hinckley isn’t that far to travel to and complain.

At £11,350 (plus £150 if you want a white bike) the Triumph Speed Triple S is at the top end of the super naked scale. There again, it does come with a good electronics package, TFT dash and a high level of build quality. It’s only when you see the all-singing RS model is just £1900 more that you start to question its price tag.

The super naked motorbike market has gone berserk in recent years and the old 1050 feels more like a middleweight by comparison. The 2021 Triumph Speed Triple 1200 RS marked a big step up in performance for the model, but it has to compete with weapons like the Aprilia Tuono V4 Factory, the superbike with flat bars BMW M1000R and the gorgeous but also powerful Ducati Streetfighter V4S.

While you get traction control and ABS, they aren’t angle-sensitive, which is a shame. The Showa suspension is fully-adjustable, you have Brembo monoblock radial brakes, four rider modes, a TFT dash, Pirelli Diablo Supercorsa tyres, cruise control and back-lit switchgear. It’s all very impressive - but again, until you see the RS’s spec list.

Model history & versions

Model history

Over the years there have been several significant changes to the Speed Triple range. In 1994, the 885cc steel-frame Speed Triple was launched. In 1997, the second-generation of Speed Triple, the T509, gained the iconic twin headlight look. The following year, 1998, the motor grew to 955cc. In 2005, the ‘underseat  pipe’ 1050cc Speed Triple was launched. In 2008, the Speed Triple 1050 was updated with new wheels, brakes and subframe. In 2011, an all-new Speed Triple was launched with sportier handling. The first Speed Triple R arrived in 2012 with Öhlins suspension and most recently in 2016 the Speed Triple was updated and available in R and S forms.

Brilliant bike for the road you don’t need the RS or anything more power handling brakes etc are perfect for today’s roads

Ride quality & brakes 5 out of 5

Ride is superb At it’s best on fast A roads where the engine is faultless, you can either leave it in a high gear and just roll the throttle on or off or you can play with the gearbox either way it’s bloody brilliant getting about 150 miles to a tank average which by that it’s nice to have a leg stretch. My wife has been on the back a couple of times and has said !!! Urm no !!! Make of that what you will !!!

No worries with build quality or reliability had the recall for the quick shifter all professionally done by Webb’s of Peterborough

Value vs rivals 4 out of 5

Servicing still think is a bit expensive but probably no more than any other big bike getting about 50 mpg average so good for the performance

Equipment 5 out of 5

Bought it when it was 5 months old with next to no miles came with arrow cans quick shifter carbon tail tidy plus extras have since fitted radiator and oil cooler protector all highly recommended especially arrows sounds fantastic bikes black the only colour in my view for a speed triple !!, little fly screen helps but how much I’m not sure , it came with supercorsa’s which were brilliant but didn’t last long was recommended Rosso 2’s by Mark of mobile bike tyres ( highly recommended) and they are spot on

Buying experience: Bought it from triumph of lowestoft no problems very professional good bunch of guys

The engine, suspension, braking, styling and new dash are awesome. The twin exhaust sound great, rider modes and back lit switchgear are brilliant with the added bonus of cruise control. The only downside I’ve had are the tyres which are superb in the dry but not to good in the damp or wet. Handlebars are quite buzzy.

Ride quality & brakes 4 out of 5

Ride is a little on the stiff side for the poor road conditions. I do plan to take it to have the suspension set up for me.

Engine 5 out of 5

Absolutely fantastic, loads of torque, smooth delivery and plenty of speed when needed or wanted.

Reliability & build quality 5 out of 5

Build quality is brilliant. The only issue I’ve had is the quick shifter wasn’t tightened up properly when I collected the bike which resulted in a nut falling off and I couldn’t down shift but managed to limp back to triumph who sorted straight away. Had a recall on the front brake pads which I never had an issue with anyway.

Value vs rivals 4 out of 5

Triumph have fixed service costs depending on engine size and if it’s an annual or major service.

Equipment 5 out of 5

The triumph windscreen is great and very good value. The up and down quick shifter is slick and a must. I’ve just fitted bar risers to take some weight off my wrists and hands as I am a shorty. Rad and oil cooler guards are recommended. If you plan to use the bike in the wet I would recommend a tyre change (my next change)

Buying experience: Bought the speed triple S from Triumph in Watford. It was on special offer at £9.999. Highly recommend this dealership as the staff are awesome and made the buying experience feel special.
