A New Classic-Styled Sidecar Scooter Option Lands Stateside

Genuine Scooters has announced that the Royal Alloy Grand Prix 300S sidecar scooter combo is now available in the United States. This marks a significant moment for riders seeking an affordable, classically-designed alternative to existing sidecar options on the market. The company has engineered a purpose-built sidecar specifically designed to work seamlessly with the 2027 Grand Prix 300S, eliminating guesswork and the need for aftermarket modifications.

The 2027 Royal Alloy Grand Prix 300S is powered by a liquid-cooled, four-stroke single-cylinder engine displacing 278 cubic centimeters. The fuel-injected powerplant produces 21.5 horsepower and uses a continuously variable transmission for twist-and-go operation. Riders can expect a top speed around 80 miles per hour from the scooter alone, though this will be lower when carrying a passenger in the sidecar.

The scooter itself includes several modern conveniences. An anti-dive front suspension system paired with anti-lock brakes provides confidence in varied riding conditions. LED lighting surrounds the vehicle, while 12-inch wheels wrapped in Pirelli tires handle the road. Genuine Scooters backs the machine with a two-year unlimited mileage warranty, providing peace of mind for new owners.

The Sidecar: Design and Features

The engineered sidecar for this model showcases purpose-built construction. Its fiberglass body keeps weight manageable while offering durability. A windscreen protects the passenger from wind and weather, while a locking trunk provides secure storage for personal items or gear. Front and rear integrated brake lights ensure visibility to surrounding traffic, a safety-focused detail that demonstrates thoughtful design.

One important limitation to understand: this sidecar is exclusively available as part of the 2027 Grand Prix 300S package. Genuine Scooters does not sell the sidecar separately, nor will it retrofit earlier Grand Prix 300S models. This means buyers must purchase the complete combo to experience this sidecar option.

Pricing and Value Comparison

The 2027 Royal Alloy Grand Prix 300S carries an MSRP of $6,199 for the scooter, with the sidecar adding $3,199. This brings the total package to $9,398 before destination charges and optional accessories. For budget-conscious riders, staying under the $10,000 threshold represents meaningful value in the sidecar market.

Consider how this pricing stacks up against competitors. A new Vespa GTS 310 HPE alone costs around $8,000, and a typical aftermarket sidecar installation adds another $4,000 or more when professional mounting is included. If you’re considering a motorcycle-based sidecar rig instead, the Ural Neo, built on a larger 500-cubic-centimeter platform, starts at $14,000. The Royal Alloy combo offers a genuine price advantage compared to these alternatives.

What This Means for Shoppers

This release expands the sidecar marketplace at a critical price point. Riders have traditionally faced limited choices when seeking stylish, new sidecar combinations. While motorcycles dominate sidecar conversations, scooters represent an underexplored segment in the sidecar world. The Grand Prix 300S with sidecar appeals to riders who want classic styling without the premium pricing of European heritage brands.

The engineering integration between scooter and sidecar matters significantly for buyers. Having a manufacturer-approved sidecar designed specifically for a given scooter model eliminates compatibility uncertainties. No guessing about weight distribution, braking dynamics, or handling characteristics. Genuine Scooters has optimized these factors from the factory.

For those curious about sidecar riding itself, the experience deserves attention. Sidecar rigs attract enthusiasts and casual admirers alike. There is something distinctive about three-wheeled operation that generates genuine interest from the wider public. If you enjoy turning heads and creating conversation wherever you ride, a sidecar machine delivers that reward.

Next Steps for Interested Buyers

Shoppers serious about the Royal Alloy Grand Prix 300S sidecar package should visit authorized Genuine Scooters dealers for firsthand evaluation. Sitting in the sidecar, examining build quality, and experiencing how the complete rig feels matters before committing. Given the $9,398 investment, test-riding both the scooter and sidecar combo makes sense.

Consider also what you’ll use the sidecar for. Whether transporting a regular passenger, hauling gear, or simply enjoying weekend rides with a companion, the sidecar fundamentally changes the riding equation. Understanding local regulations around three-wheeled vehicles is important before purchase, as rules vary by state and municipality.

The arrival of the Royal Alloy Grand Prix 300S sidecar package represents genuine news for American scooter buyers. An affordable, purpose-engineered option now exists in a market previously dominated by expensive modifications or premium-priced alternatives. Whether this represents your ideal sidecar solution depends on your budget, style preferences, and riding needs, but the choice itself is valuable.
