r/TriumphBonneville

I leave the huge beaches of Sands campsite in Gairloch on my Triumph Bonneville and ride south through the gorgeous highland scenery to try and beat the bad weather to the infamous Bealach na Ba pass, leading to Applecross. Hoping to meet my friend Rory on the way, but he has much further to come - will he beat the weather and make it up the pass on his Harley Davidson?
The Bealach na Ba used to be the route cattle would be driven between the villages of Tornapress and Applecross in Wester Ross. The pass itself is a single lane road, 11 miles long, and in the middle its hairpin bends climb from sea level to over 630 metres within 6km, creating gradients around 20%, and has the steepest ascent of the roads in the whole of the UK.

I recently bought a 25 Bobber and I’ve been looking around for some common add-on parts, especially exhaust-related components like an X-pipe / decat and similar accessories.

What I’m finding is that basically every reputable source (based on my searches), such as British Customs, Motone, and even a lot of their distributors are either showing parts as out of stock, not clearly listing 2025 fitment, or only listing fitment up through earlier model years.

I know the 2021+ / Euro 5 bikes changed some things, and I’ve seen references to certain bikes having welded mid-pipes vs clamp-style connections. For what it’s worth, I checked mine and it does have clamps, so I’m trying to figure out whether this is actually a compatibility issue, a supply-chain / inventory issue, or if some of these companies are just not making certain Bobber parts anymore.

Has anyone with a 2025 Bobber successfully found and installed an X-pipe or similar exhaust add-on recently?

A few specific questions:

• Are British Customs / Motone / Hitchcox parts for the Bobber being discontinued, or are they just temporarily out of stock?
• Are there 2025-specific fitment differences I should be watching for beyond the clamp vs welded-cat issue?
• Any vendors you’d recommend that are still actively supporting the newer Bobbers?

Not looking to start a legal/emissions debate, just trying to understand whether I bought at a weird time, or if aftermarket support for the newer Bobber is drying up.

I recently got a 2014 T100, and it has the standard fuel cap which can’t be locked.

Has anyone ever had any problems with that? I was thinking of replacing it, but I might just be paranoid.

I mean, who would either try and get fuel out or other stuff in?

I have a 2012 t-100 and it’s not starting. It sat for too long and the gas went bad. The last time it started up fine, but died on the way down the block.

I have drained the tank and put in a gallon of fresh 93 octane

The spark plugs were black so I replaced them

We tested the fuel injectors and they are activating

The bike cranks but doesn’t fire.

This is the error code I get from scanning obd port P0122 — Throttle/Pedal Position Sensor/Switch “A” Circuit Low

Has anyone run into a similar situation? Any advice for things to check next?

Been riding a 2001 Bonneville for years (age says it all) but as the bike has aged 25 years, so has the driver. It was always a bit big for me, never minded, could kind of lean it to one side or the other. Over 65 now--that's not cozy to say the least.

Got a Texavina seat, lowered the boots on the ground height by 3 inches. Perfect.

I had the OG Triumph Seat on for years (never a complaint-long rides etc.) Is the Texavina firmer (yes), a bit less comfortable (yes). Is it working well in terms of being able to flat foot--so much better. Is it working well in terms of backing it out of parking spaces and the driveway--so much better.

Hi Gang,

I'm thinking of getting some new springs for the Bonnie (Front and back probably, but rear first for sure). Hagon seem to be the ones to go for but there is only 1 option - the cheapest - available on their SE page at the moment as opposed to the wealth of styles and colours for the spoked bonnevilles.

Question - is the £147 model an actual upgrade to the OEM shocks or do I need to look elsewhere. Square-deals have the YSS shocks (in a much less cool colour) for example at £250, but they would not be so customised as the Hagons.

Any thoughts?

(Is the front worth doing..?)

2016 Bonneville; I went for a glorious ride, parked the bike, and now I cannot for the life of me figure out how this function turned on and how the hell to turn it off. I am at a loss here! What am I doing wrong? I can't even turn the engine on, just the indicator lights come on.

I've been making adjustments to my 2014 T100 since I've got it. Seems like a very long work in progress. Main things changed are:

- taillight (british customs)

- headlight bracket , turn indication relocation + key relocation

- suspension back (hagon nitro)

- suspension front (hagon progressive)

- tor exhaust

- heat wrap

- steering damper

- tracker bar (biltwell)

- torker grips (biltwell)

- bar end mirrors (motogadget)

- chain guard (british customs)

- flat gauge mount (motone)

- TTP performance tune (airbox adjust, o2 sensor removal)

- crankcase breather filter

- headlight grill (Raisch)

- stryke seat (alo's cafe)

Thinkig of swapping the footpegs for something else. Anything else you'd change? Note that I'm not a mechanic (so nothing too complicated) and ride in the rain (so while a tail tidy looks awesome, I just don't think it's practical).

I have no paddock stand and the bike lacks a centre stand. How do I tighten the chain or is it just easier to take it to the mechanics and get it tightened?

So having an issue starting which has repeated for the third time n not sure what to make of it. Bike is 2012 T100 EFI.

Battery is 8months old. Measured 13.3V running voltage yesterday which seems ok from searches.

Here's the startup sequence from today:

1. Battery on trickle charger overnight. Measured 13V today before trying to start.

2. Bike in neutral, kickstand down.

3. Turned key n "boot sequence" lights, pump etc all look/sound normal. Display shows bikes in neutral.

4. Pressed starter button and nothing happens like an interlock is stopping the starter motor from getting juice.

5. Next, like 30s later, don't move air anything but put kickstand up, press starter button n bike turns on.

In the past I've turned the bike on with KS down in neutral n have had no problems. Confused if this has to do with the KS interlock or other bc the battery seems ok from voltage. Any ideas? TIA
