Talkin’ TT: A first-timer’s guide to Isle of Man TT lingo

The engines are roaring, the flags are waving and if you’re standing anywhere along the Mountain Course wondering what on earth a “Superstock” is or why someone just shouted “they’re on the pipe!”, you’re not alone. If you’ve just moved to the Island or you’re finally checking TT off your bucket list, there’s no shame in being a bit lost in the lingo.

Here’s a quick crash course in TT speak to help you blend in a little better, cheer at the right moments and maybe even impress your mates at the pub after the race.

“Bushy’s”

If someone says they’re off to Bushy’s, they’re talking about the famous beer tent (and now beer garden at the Villa Marina in Douglas) that pops up during TT. It’s a go-to spot for race fans, live music and a post-lap pint.

“Mad Sunday”

Once upon a time, not so long ago, Mad Sunday was an informal tradition where spectators could ride the TT course themselves on closed roads, with marshals and plenty of enthusiasm (and the occasional crash). But from 2023, the practice was retired to make room for a revamped racing schedule.

“Signpost Corner”

This is one of the final corners of the course. When riders hit Signpost, they’re heading down towards the finish line. You might hear talk about the “lights on at Signpost” - that’s the dashboard lighting up, signalling they’re in the final stretch and giving it everything.

“The Mountain”

No, not the one from Game of Thrones. When locals talk about The Mountain, they mean the Snaefell Mountain Section of the course. It’s the highest and most dramatic part of the lap. Think open roads, sweeping views and serious speed.

“On the Pipe”

This old-school phrase refers to a two-stroke engine hitting its power sweet spot, meaning maximum performance and peak revs. You won’t hear it as much these days (modern TT bikes are mostly four-strokes), but it’s still used to describe a bike that’s absolutely flying.

“Lap Record”

This is the ultimate bragging right. The fastest ever lap of the 37.73-mile course. As of 2023, Peter Hickman holds the record: 16 minutes and 36.114 seconds, at an average speed of 136.358mph. Madness!

“The Senior”

The big one. The Senior TT is the most prestigious race of the fortnight, traditionally held on the final day of the fortnight. Fastest bikes, top riders, ultimate glory.

“Bump Start”

Sometimes the electric starter on a bike gives up and riders have to do it the old-fashioned way: push the bike to build up momentum, pop it into gear and hope. You might spot this during warm-up or if a bike stalls unexpectedly.

“Sector Times”

The course is split into timed sectors and riders’ progress is tracked throughout. These split times help fans, commentators and teams see where time’s gained or lost. After all, the TT is one long time trial.

“Marshals”

Marshals are the unsung heroes of the TT, responsible for ensuring the safety of both riders and spectators. They manage track access, respond to incidents and communicate vital information during races.

“Scrutineering”

Not as scary as it sounds! Scrutineering is the safety and technical check each bike goes through before hitting the course. Officials inspect everything to make sure the machines meet strict TT regulations. Think of it as a very intense MOT.

“The Course”

Shorthand for the Snaefell Mountain Course, the full 37.73 miles of public roads transformed into a legendary racing circuit. It’s fast, technical, unforgiving…and utterly iconic!

“Sidecars”

It’s not just solo riders; sidecar racing is a TT tradition in its own right. One person rides, the other (known as the passenger or co-rider) shifts their body weight to help balance and steer. A chaotic, precise and seriously entertaining performance to watch.

“Practice Week”

Before race week comes Practice Week (also known as Qualifying). It’s the first week of the TT fortnight, where riders learn the course, test setups and qualify for their races. The roads are still closed, the speeds are still wild and it’s a great time to watch without the full race day crowds.

“Superstock””

This race class uses bikes that are very close to what you could (in theory) buy from a showroom. Few modifications are allowed, which means it’s all about rider skill. No hiding behind fancy upgrades!

RL360 has been sponsoring the Superstock Race since 2002 so, naturally, we think this is the best class.
