Triumph’s decision to revamp the original Rocket III into a streetfighter was an interesting one. Why? Because it hardly fits the bill – stripped version of a sports bike with oddball looks – because of its custom-biased specs of long wheelbase and weight, but it works. In 2020 this bike was replaced by the third generation Triumph Rocket 3.

Rear suspension units were softened off over the previous model for a more comfortable ride and the seat height upped by 10mm to 750mm. The best change was the moving of the footrests back by 100mm and down 20mm to make the seating position more natural, read comfortable, than the old custom feet forward style.

The Roadster did a good job of hiding its 367kg (wet) weight and was actually a very easy, nimble bike to ride. Ground clearance wasn’t great, but the footpeg blobs were replaceable. Good brakes, too. ABS was standard on the Roadster and tuned nicely for big braking action before chiming in.

Handling was more machete than scalpel, but it got the job done and was surprisingly capable for a lump that could create its own solar eclipse.

The 2294cc triple-cylinder has been around in various guises since 2004 but in 2009 a ruck of mods upped torque to a mighty 163ftlb, and power to 146bhp. The revised exhaust layout including bigger volume silencers was the reason for the power increase – and incredible noise at high rpm.

Forward thinking was crucial along with a right foot that’s poised over the back brake to settle matters down, but that roar as the engine reaches 5000rpm or so was a treat.

Gearbox shift mechanism was updated for sweeter shifts and the clutch and shaft drive were beefed up to cope with the extra output… and tomfoolery the Roadster eggs you into.

There were a few reported niggles with the very first Rocket models e.g. rear shaft drive seal. Chrome finish could suffer if not looked after carefully.

MCN spoke to Adrian Clancy, head mechanic at Total Triumph in Taunton, Somerset, about living with the Rocket III.

"We get quite a few Rocket IIIs in, but they’re only really ever visiting for tyres, brake pads and services. The early bikes had a silver engine and I think it was 2006 or 2007 that they went to black engines and the colour change coincided with a lot of upgrades to the engine and gearbox to keep engine noise and harshness down and to make them a bit more refined.

"There are some things to watch out for on them, and the biggest issue I’ve seen over the years is dodgy ignition switches. You turn the ignition on and if you fiddle with the key the ignition can cut out – we’ve had to change quite a few barrels over the years.

"They’re also heavy on rear brake pads, which is to be expected, and heavy on rear tyres, which probably goes without saying. Some riders complained about clutch slip on really early models, but I remember the clutch springs being upgraded on later bikes.

"There were also customers complaining about an oil leak coming from the side of the engine. It turned out to be a preservative that was sprayed on the bike while it was stored. It was cleaned off before sale, but some of it would get trapped behind the side-mounted oil tank.

"When the engine got up to temperature the preservative would melt and drip down the side of the engine and look like an oil leak. If you see one that’s been sitting up over winter or in a showroom for a long time you might see fork seals starting to leak.

"But more often than not, all it takes to sort it is to dry it off and go for a road test. The seal isn't damaged, it just relaxes and allows a tiny weep of oil out, so going for a spin will make it good again.

"The later you can buy the better. If you stick to the black engines you’ll be alright and if I had to narrow it down I’d say one from 2009 on is the one to go for."

The Rocket III holds its value well so don't expect to see many low mileage second hand bargains.


4 out of 5 (4/5)

Shaft drive for reliability and low maintenance was good. ABS also good. And heavy use of black coating throughout the bike was okay for the styling exercise. Little details like the addition of digital readouts for fuel range, gear indicator and time of day were also nice touches. To sum up: it’s all there and it works – this includes the biggest production motorcycle engine ever.

needs a much better detent spring,,perhaps one that fits better to its joining ends so it catches itself when it breaks instead of dropping into the engines oil sump in two pieces and you then have problems that dealers just love to fix for $$$$

When Triumph first bought out the Rocket111 I loved it straight away. I read the statistics and thought wow it was sort of like you know when you were a kid and you liked a certain popstar yeh i know and to cap it all I was 56 at the time. do I have moan? I wish I could take the luggage off a bit easier (the frames) would I recomend it to a friend definitely.

I have never had anyone on the back as for the bike I want get the seat altered (i'm a short ass) it is fairly comfortable though I have not done any real long journeys with it.

Engine 5 out of 5

I like the performence when I'm on a run somewhere its hard to take the stupid grin off my face.

Reliability & build quality 5 out of 5

I keep the bike in the garage so there is very little rust on it i have to clean the pipes now and then never broken down nothing failed.

Value vs rivals 4 out of 5

When I first got the bike there was 3000 miles on the clock now Ithink its about 5000 it gets a bit juicy sometimes if I don't watch the speed.

Equipment 4 out of 5

I like the seating position and the handlebars though I wish the seat was a little lower. Tyres well I'm happy with them so far.

Buying experience: I had a Suzuki 1400 at the time of purchase which I traded in and so got a couple of grand off for that. The bike was actually up for 11grand at the time I miss the 1400 though.

An incredible British built beast of a machine. Completely unique. Buy one, you will not regret it.

Compliant ride that is not overly firm yet allows sharp steering for a bike that weighs over one third of a ton. Pillions love the large rear seat and you don't even know they're there.

Engine 5 out of 5

Incredible torque and relentless acceleration. You can pull away in 5th! Perfect bassy growl of an engine note that could wake the dead.

Reliability & build quality 5 out of 5

Beautiful build quality. Everything feels massive and completely solid.Starts first time, every time. It's a huge engine with a huge battery so needs to be turned over or trickle charged to ensure it starts without regular use.

Value vs rivals 5 out of 5

Reasonable running costs for the size of the bike. Annual servicing is just over £200 at a main dealer. Valve clearance check is £90.

Equipment 5 out of 5

Range to empty, gear indicator and clock. Well equipped with Triumph Datatool 4 alarm/immobiliser. Metzler tyres are supreme and inspire confidence.

Buying experience: Bought from a dealer for a reasonable price. These machines hold their money incredibly well so a worthwhile investment.Buy one, I promise you won't be disappointed.

The thing that lets the bike down is the ride I can feel most of the bumps, I have put progressive springs on the front and will change the suspension on the back when funds are available. I know tyre pressures are crucial and they are checked before every ride.

Probably go about an hour before a break, it's a big saddle but not that comfortable.

Engine 5 out of 5

The Engine is Awesome (the best best part of the Bike) it pulls well in 1st-3rd (that's when it's unrestricted) but it's no more powerful than my K1600GT BMW (and the BMW goes around corners) The bikes engine would probably take you to the Moon and back no problem (I have been told that the Engines are Bulletproof.

It had a top engine casing replaced under warranty cos when I bought the bike with 11000 miles on the clock there was no engine number where it should have been. The Triumph dealer Pure Triumph of Wellingborough have stamped the engine. Number on now,

Value vs rivals 4 out of 5

The third service is due the dealer said it would be about £200.00 but the next yearly service next year could be £500.00 (ouch) because the Valves have to be done then).

Equipment 4 out of 5

The Equipment is not bad pretty basic but I didn't buy it for it equipment. Could do with Cruise Control (that's a personal thing)

Buying experience: I bought from a dealer - the experience was good. Nina at Pure Triumph in Wellingborough looked after me very well.

New to Triumph Motorcycles; Best feature is the pull you get right off the line; the brakes are very good as well as the handling. Also, like the spartan rawness of the rocket not a bunch of electronics/worthless junk to distract the rider. Shifting is a little loud but you get used to that as well as neutral could be easier to find. The weight really isn't an issue once it is moving. I can tell you keeping proper tire pressure absolutely crucial especially with this bike. Riding on an off during the winter months you can definitely tell when one or both of tires is low. Also, want to add i got this last year 2015 March for an absolute steal (2014 R3R) for $11,990 with only 53 miles an on it.

Had to replace crankshaft sensor; thankfully the factory warranty covered the cost. Also from the 1st service your next oil change is not until 10K miles later :)

ABS is standard on the rocket roadster.

Quick summary: 1. Needs a 6th gear (it nearly throws you over the handlebars at 140mph!) 2. The handling nearly killed me! It doesn't go round corners... at all! If anything was coming the other way I have no doubt I would be dead. (Heart in mouth, turd in pants 'n' all). 4. The shaft drive's a bit twitchy in the wet and on roundabouts. 3. Otherwise... ridiculous fun. The novelty of the power coupled to the riding position never wears off.
