I recently purchased a '15 T100 from a private seller. I only did a short test ride, but the bike seemed to be working well. I trailered the bike home and when I tried to ride it the next day it was difficult to start and would die during idle. I took it to a local mechanic who replaced the...

Having a 2018 Bonneville T100 Black and found it vibrates every time over 100kmh on highway or any time over 4k rpm. Took it to the dealer and staff their said it’s nothing wrong after 20 min inspection: vibrations may caused by no mufflers ( Last owner took them off ). I also feels some power...

Hello everyone. I have a 2013 Triumph Bonneville T100, I'll give some back ground into the bikes history before I explain the main issue I found. Bought the bike Brand New. So I'm the original owner. Rode the bike very very little the first two years or so. Was last registered in 2015. Living...

Hi from Sunny Derbyshire. I am John a 63 years young and been keen on motorbike since my teenage years. I am hand with tools but no expert. I have a Honda Deauville for my work horse, great bike. I have bought1967 sort of T100R. Just working to put it on the road for summer with some work...

I’ve got a 2003 Bonneville T100 and recently relocated to Las Vegas from NY. Roads are well kept here but because little rain the roads build up oil slick patches and in the hottest months are white knuckle riding for me. I’ve felt my rear wheel slip often. Any recommendations for a hot...

Hi All I have been contemplating some upgrades to my T100 ... Thinking about doing the TEC camshaft and (probably Meerkat) decat. Was just wondering if anyone has done this that can share experiences. I am curious about performance, and also additional parts required for the cam upgrade. Did...

Hey all, Upon purchasing my bike in 2018 I immediately replaced the seat and lights which left me with a rather large box with the original seat and lights taking up space in my basement. Is there any interest here? Anyone want the whole lot for $150 inclusive of shipping? Not looking to get...

Hi All, Longtime reader, first time poster! The Problem: My 2008 Carbed T100 has had an idle stutter since I bought it a year ago. What happens is when the bike first starts up from cold and the choke is pushed in, she idles perfectly. Then once the engine heats up (after sitting at idle for...

Some of you may remember my posts here quite a while back about working on my dads old triumph with him while he fought cancer. Long story short he lost the fight and without his technical experience the triumph sat. About 6 months ago I reached out to a local (PNW) classic motorcycle club and...

I bought a used 2017 Triumph Bonneville T100 and a car ran into me, breaking a few parts on the right side. Somehow, the brake pedal has been on backorder for months and I can't find any custom part to replace it. Would you have anything compatible with part t2023057 ...

Hi, I just purchased my T100 2003 a couple of weeks ago and I want to give it some proper TLC. The former owner didn't really spend much time keeping the bike sparkly as it deserves. Now I don't have one of those all black or all shiny chrome engines. Mine has mat cover and I'm not sure how I...

Hey everyone. New to this community and new to riding bikes! I recently got my first bike a 2016 air cooled Triumph T100 (865cc). Been riding for close to 6 or 7 months now, and mainly have only changed physical things on the bike like headlight and seat and mirrors. Recently though I installed...

Some of you may have seen my earlier post about my starting and running issues on a recently purchased 2014 T100. Still not fixed, and I’m waiting for an appt at my local garage. In the meantime I put some Seafoam in the tank and have run the engine a bit. New development: it has been...

When I hook up my battery, is it normal for the horn to still work even with the bike turned off ? I have bought a new battery and seems after a couple of days the battery has lost it's charge. Thanks for your support.

So, I'm finding it surprisingly difficult to confirm the stock handlebar measurements for my 2014 T100. There are various numbers floating around, and although I've found this chart posted in a couple of threads here I am not entirely confident in it...

Hi there! I was wondering if more T100 riders have the problem of their mirrors (original) moving inwards when increasing acceleration or at high speeds? (above 120km/h - 75 mp/h). And if anyone has a solution for this... The original mirrors are (in my opinion) weirdly fitted with a single...

I’m looking for a replacement motor for my ‘06 T100 (865) and hoping some of you fine folks can point me in the right direction. I see some on eBay between $800-$1200 but don’t know how much I can trust them. Was hoping someone on here might be in the know of a good motor for sale. I’m in...

So after dragging my Bonnie out for the first time in a while I realised the airbox felt loose - discovered the plastic around the side-facing bolts (by the battery) had snapped completely on each side, and the forward-facing screws had either worked themselves loose or not been replaced after a...

I'm based in Wellington, New Zealand, and recently bought my black and white 2011 Bonneville T100. The person who sold me the bike included a comfortable King and Queen touring seat, reverse cone megaphones, UK-flag gas cap, faux leather panniers with home made frames, Ventura luggage rack...
