The custom motorcycle scene is quickly growing, as riders look to own unique, stylish, and customized motorcycles that stand out from the thousands of mass-produced models. There are typically two routes riders can take to own a bespoke bike. They can commission one of the many capable custom shops out there to build it, or do the work themselves. The former option is a lot easier, but it is usually on the expensive side. The latter choice is more fulfilling as it allows for more personalization, but most people lack the necessary skills, training, or equipment to take on a custom build.
This is where bolt-on motorcycle kits come in; bolt-on kits are mounted onto motorcycles using stock mounting points, eliminating many hassles and expenses involved in a typical custom build.
10 Autologue Design Reck Kit
When brand new, the Royal Enfield GT 650 is a sleek, cafe-inspired modern retro-styled motorcycle that anyone would love to throw a leg over. However, this didn't stop India's Autologue Design from taking the bike's café vibe a step further with its Reck 2 kit.
This bolt-on kit comprises two pieces; a new, long-tail cowl that can be easily removed on the fly and a front quarter fairing. Though it's made up of only two pieces, the Reck kit is surprisingly transformative. It's also incredibly affordable compared to other kits, making it ideal for those on a tight budget.
9 Hookie Co. Yamaha XSR700 DIY Moto-Kit

Handmade in Dresden, Germany, each XSR700 DIY Moto-Kit boasts a top-class fit and finish and features high-end materials like the Alcantara saddle. All the rider needs to do is add Rizoma-style indicators and an aftermarket exhaust, and they'll have a stellar custom bike on their hands.
8 Bad Winners DIY Scrambler Ducati MotoKit
The latest generation of the Ducati Scrambler pays homage to the manufacturer's original Scrambler produced in the 60s. While many Ducati fans love this vintage appearance, a small section of them prefer a more modern look.
This is where the Bad Winners DIY kit comes in; compatible with all Scrambler models, this kit comes with a sculpted, knee-dented tank cover and a unique tail unit capped off with a stylish, ribbed leather seat. There's also a vast range of bolt-on bits available that complement the Bad Winners kit wonderfully.
7 UN1T Garage Fuoriluogo Scrambler Kit
Built in Italy by UN1T Garage, the Fuoriluogo Scrambler kit wonderfully combines a retro-style visual theme with a modern dual-sport aesthetic. It comes with a bench-style saddle, an old-school tank, side covers, a rear luggage rack, and a high-mount two-in-one side-pipe exhaust.
Contrary to the Fuoriluogo kit's vintage appearance, it offers modern performance and unmatched reliability. One of the Fuoriluogo kit's best aspects is that it perfectly complements certain existing elements of its donor, such as the grilled headlight, gold-rimmed spoke wheels and the MX-style front fender.
6 Paolo Tex Design XB Buell XB12 Kit
This kit from Paulo Tex adds a muscular and aggressive look to the Harley-powered Buell XB12 sportbike. The kit looks a lot like the Buell-based Ronin 47 bikes and uses a collection of laser-cut aluminum and 3D-printed ABS plastic components.
Despite altering the XB12's appearance dramatically, the kit maintains the stocker's suspension, rim-mounted brakes, and wheels. Its minimalistic and aggressive tail section is complemented by angular new tank covers that give the sportbike an attack-ready, hunched-forward stance, particularly when combined with its sliding telescopic fork cover.
5 NMOTO BMW R NineT Nostalgia Motorcycle Kit
Introduced in 1934, the BMW R7 was a wild prototype that's considered to be among the most substantial motorcycle designs of all time. Sadly, since only one example of the two-wheeled masterpiece was created, owning an R7 has been impossible, even for the wealthiest Beemer enthusiasts.
But now, Florida's NMOTO is giving people a chance to own a valuable piece of BMW's rich history with the Nostalgia kit. This kit comes with 74 individual pieces that do a great job of making the R nineT look like the pre-war masterpiece. Every element of the Nostalgia kit is spot-on, from the fishtail exhausts to the flared fenders. Customers also get a myriad of color, upholstery, and accessory options with the kit.
4 HotBodies Racing SV-R Race Bodywork Kit
For decades, the venerable Suzuki SV650 has been a cult favorite thanks to its tractable power, bulletproof reliability, unbeatable value, and versatility. However, most motorcycling enthusiasts have always felt that the SV650 lacks style, so HotBodies Racing built the SV-R Race Bodywork kit.
This kit is made from an ultra-lightweight fiberglass fabric with reinforced mounting points and features a tail section, nose, full fairing, and a belly pan inspired by Suzuki's MotoGP bike - the GSX-RR. It can also be easily modified to become street-legal by adding signals, a headlight, and a taillight.
3 GG Retrofitz Rocket Street Kit
The Yamaha YZF-R3 is already a great bike, but the Rocket Street kit from California-based GG Retrofitz takes it to a whole new level by turning it into a sleek neo-vintage road-racer. This kit offers the appearance of a professional-level build in an affordable, easy-to-install package.
The kit has an eye-catching design that was largely derived from the iconic oil-burning Yamaha TZ racers of the 70s, albeit with a modern twist to attract younger riders. GG Retrofitz also sells a track-only version of the Rocket Street kit for those who need something a bit sportier and meaner-looking.
2 Phil Little Racing SXR Sportster Street Tracker Kit
American icon Harley-Davidson has a long, rich, and successful history of flat track racing. Unfortunately, the brand doesn't offer a flat-track inspired bike apart from the MoCo XG750R. Luckily, Phil Little Racing has a kit that can transform the popular Harley-Davidson Sportster cruiser into an all-out street tracker.
The SXR kit pays homage to Harley-Davidson's decades of dirt-oval dominance with its tear-drop fuel-cell and classic tracker tail. It's also 100 percent street legal as it comes with a low-profile headlight, a plate-hanger, and signals. Those working with a tight budget can purchase individual pieces of the SXR kit separately.
1 BeOn 450 GP SuperSingle Kit
When it comes to versatility, no other kit on this list beats the 450 GP SuperSingle kit from BeOn. This kit can transform a standard 450cc KTM dirt bike into a competitive, lightweight track weapon. It comes with a modified rear shock, a 43mm USD fork, a set of Dunlop racing slicks, a 7075-aluminum rear sprocket, Izumi chain, and radial-mount Brembo brakes.
The kit also includes a full set of fiberglass bodywork that makes it look like a Grand Prix racer. There's a lot to love about this kit, but arguably the best thing about it is that it allows riders to own just one motorcycle that does it all; Supermoto, commuting, off-roading, and road racing.
