According to Google: Recent 2025/2026 rumors suggest Triumph is working on an emissions compliant Big Twin. Reports suggest a new Storm is intended to feature a modern, high-torque parallel-twin engine, updated electronics, rider aids, a more refined chassis and an aggressive, modern look. ...this'll fill the gap in Triumph's lineup for a heavy muscle cruiser.
Anyone else hear about it?

Google Ai says. As of May 2026, there is no official confirmation or concrete evidence of a new, large-displacement parallel-twin cruiser in development designed to directly replace the 1600cc/1700cc Triumph Thunderbird, which was discontinued in 2018.
While rumors occasionally surface, Triumph's current "big" cruiser strategy revolves around the massive 2500cc inline-three engine, not a new parallel twin.

 
Experience is something you get just after you needed it

Damn. And I read the new Thunderbird would have to weigh in the 600 lb. (272 kg) range.

Ok. Something may be brewing....



...An AI-generated 1200cc Thunderbird concept bike and spec sheet. But there'll be a modern monoshock in place of the traditional dual shock configuration and no instrumentation on top of the gas tank. Also, the bike comes in red and blue.

Estimated Performance: 
* Horsepower: ~103.5 hp @ 7,750 RPM
* Torque: ~82.6 lb-ft @ 4,250 RPM
* Estimated Weight: ~510 lbs – 540 lbs (231 kg – 245 kg)
* Construction: Cast aluminum rear subframe & swingarm to hit target weight. 
Accessories and Upgrades: 
* Vance & Hines Slip-On (stubby) mufflers
* Ohlins fully adjustable rear shock
* CNC-machined adjustable levers
* High-flow air intake kit
* Forward control relocation kit
* Bar-end mirrors
* Pillion seat delete cowl
* LED bullet turn signals
* Dress bars (engine guards)
* Aluminum sump guard
* Increased ground clearance
* Triumph Protect+ alarm system 
Electronics & Dealer-Installed Performance Kits: 
* Stage 1: Breathability & Mapping (+8 to 10 hp)
* Stage 2: Aggressive Cam Kit (+15 to 18 hp) 
Hypothetical Launch Date: October 2028

If you consider hp/torque/weight ratios between the Rocket and 2028 Thunderbird, the Rocket no longer dominates.
Rocket: ~179.5 hp/Torque ~166 lb-ft./Bike weight 700 lbs. New Thunderbird (stage 2): ~121.5 hp/Torque ~95 lb-ft./Bike weight 540 lbs.

This'll bridge triumph's muscle cruiser gap. I think it's perfect.

Except.... It doesn't look like much.

Maybe Triumph should move its factory to the US, setup shop in Arizona or Texas. They'd finish off HD and become the biggest, baddest bike on the planet. ;-)
One thing f'sure, AI will never know anything about motorcycles until it rides one.

Design is in beginning stages. ...picture new monoshock suspension, tank, Vance & Hines exhaust, LED turn signals, etc. To use a CA phrase; that's sick!
Oh, and 121 HP
