Imagine transforming one of the most powerful and iconic muscle bikes on the road into a head-turning sidecar rig. That’s exactly what Watsonian Sidecars has done with their new fitting kit for the Triumph Rocket 3. But here’s where it gets controversial: is this a genius upgrade for adventure seekers, or an extravagance reserved for the elite? Let’s dive in.
Watsonian Sidecars has unveiled a bespoke fitting kit designed specifically for the Triumph Rocket 3, a cruiser that’s already legendary for its jaw-dropping performance. With models from 2020 onwards pushing out up to 180 bhp and 166 lb.ft of torque, this bike is a beast. But adding a sidecar? That’s a whole new level of engineering precision.
The kit features a custom subframe that provides mounting points for the sidecar’s lower arms. And this is the part most people miss: these arms aren’t just bolted on—they’re precisely positioned to ensure the sidecar stays firmly attached to the bike, even when you’re harnessing all that power. It’s not just about stability; it’s about safety, especially when you’re dealing with a machine this potent.
But there’s more. The subframe also allows engineers to fine-tune the axle lead—the distance between the sidecar wheel spindle and the bike’s rear axle. This might sound technical, but it’s crucial for smooth cornering. Get it right, and your sidecar rig will handle like a dream. Get it wrong? Well, let’s just say you’ll feel it in the bends.
The images showcase a GT version of the Rocket 3 paired with Watsonian’s premium GP700 wide-body sidecar. Decked out with a bobber mudguard, tinted screen, and black trim, it’s a showstopper. Not your style? No worries. Watsonian’s perimeter frame chassis lets you pair the Rocket 3 with any sidecar in their current lineup.
Now, let’s talk cost. This isn’t a budget modification. The sidecar alone starts at £7,995, and the subframe kit adds another £2,250. Factor in the bike—starting at £23,695 for the latest Rocket 3 Storm R model—and you’re looking at a serious investment. Even used Rocket 3s hold their value, so this isn’t a cheap endeavor.
Here’s the bold question: Is this sidecar kit worth the price tag? For £10,245 (sidecar and subframe), Watsonian promises an unforgettable adventure. But with such a niche appeal, it’s unlikely to be a mainstream hit. That said, the Rocket 3’s immense torque, stability, and long-distance capabilities make it an ideal candidate for sidecar conversion. It’s already an impressive machine—this just takes it to another level.
So, what do you think? Is this the ultimate upgrade for the Triumph Rocket 3, or a luxury too far? Let us know in the comments—we’d love to hear your take!
