Hey everyone, today I wanna talk about my little project with the Triumph TT 600. This bike, man, it’s been a journey. So, the TT 600, it was Triumph’s first shot at a proper 600cc sportbike, inline-four engine and all that. I got my hands on a 2002 model, and let me tell you, it’s been a bit of a rollercoaster.

First off, I snagged this bike because, well, I’ve always had a thing for Triumphs. This one, it’s a 2002 model, and the previous owner? Let’s just say he didn’t exactly baby it. I started by giving it a good once-over. Checked the engine, a 599cc, four-stroke, four-cylinder beast. It’s liquid-cooled, which is pretty standard, but still, it’s got that raw power.
Digging into the Guts
The first thing I did was to look up its service manual, and man, those things are a lifesaver. I started with the basics – oil change, checked the spark plugs, air filter, the usual stuff. Then came the fun part. This bike had a bit of a reputation for fuel injection issues, especially the older models. Mine was no exception. It was running a bit rough, not getting that smooth power delivery you’d expect.
- Fuel Injection Fuss: I spent a good chunk of time tinkering with the fuel injection system. It’s a bit finicky, but I managed to get it running smoother. It’s not perfect, but it’s a hell of a lot better than before.
- Handling the Handling: The TT 600 is a bit on the heavier side, about 374 pounds, but it’s surprisingly nimble. I took it out for a few spins, just getting a feel for it. The seat height is about 31.9 inches, which is pretty comfy for me. I messed around with the suspension a bit, trying to get it just right.
Engine and Performance
This bike’s got a four-stroke, transverse four-cylinder engine. It’s a DOHC with 4 valves per cylinder. The displacement is 599 cc, which gives it a nice kick. The 2001 model apparently had 110 hp at 12, but I didn’t really push mine that far. Mostly, I was focusing on getting it to run right. My 2003 model had a revised fuel injection system, which was a bit of a pain to adjust, but I got there.
Final Touches
After getting the engine and fuel system sorted, I moved on to the aesthetics. I cleaned it up, polished the fairings, and just made it look presentable. It’s not a show bike, but it’s definitely a looker now. I’m thinking about maybe changing up the exhaust system, get a bit more of that throaty sound, you know?

So, that’s my story with the Triumph TT 600. It’s been a bit of a project, but a fun one. It’s not the easiest bike to work on, but when you get it running right, it’s a blast to ride. If you’re thinking about getting one, just be ready to put in some work, especially if it’s an older model. But hey, that’s part of the fun, right? Keep the rubber side down, folks!
