The UK Super Quad scene has grown massively over the last decade. What started as backyard engine swaps has evolved into a proper industry of specialist builders who turn standard sports quads into serious performance machines. Whether you're after a hill-climb weapon, a flat-out drag racer, or a road-registered super quad that turns heads, there's a builder out there for you. Here's our round-up of the best Super Quad builders in the UK.
What is a Super Quad?
Before we dive into the builders, let's clarify what we mean by "Super Quad." A Super Quad is a heavily modified or custom-built quad bike that goes well beyond standard factory specs. We're talking big-bore engine conversions, custom suspension, stretched chassis, aggressive styling, and power figures that would embarrass most sports cars. They're the quad equivalent of a tuned hot hatch — taken to the extreme.
The UK's Top Super Quad Builders
1. Quad Warehouse
Based in the Midlands, Quad Warehouse has built a strong reputation for high-quality Super Quad builds. They specialise in big-bore conversions — taking standard 250cc–450cc sports quads and fitting them with 660cc, 686cc, and even 740cc engines. Their builds are known for clean fabrication work, reliable setups, and attention to detail. If you want a build that's as dependable as it is fast, Quad Warehouse is a solid choice.
Best for: Engine swaps and big-bore conversions
2. LRS Racing
LRS Racing is a name that comes up time and again in the Super Quad community. Based in the North of England, they build some of the most powerful quads in the country. Their drag and hill-climb builds regularly produce well over 100 horsepower. LRS are known for their no-compromise approach — these are serious competition machines built to win.

3. AMC Quads
AMC Quads have been in the game for years and are known for their road-legal Super Quad builds. If you want a super quad that's V5'd, MOT'd, and road-registered, AMC are one of the few builders who genuinely understand the road-legal side of things. They handle everything from engine conversions to lighting kits and full IVA preparation.

They're a go-to if you want a Super Quad that handles as well as it goes in a straight line. TNT also offer a range of bolt-on performance parts if you're looking to upgrade incrementally rather than going for a full build.

5. RCX Quads
RCX Quads are known for their eye-catching, show-quality builds. If you want a Super Quad that looks as wild as it performs, RCX deliver.

How to Choose the Right Builder
Choosing the right Super Quad builder comes down to a few key factors:
- Your goal: Are you building a drag racer, a hill-climb weapon, a road-legal cruiser, or a show quad? Different builders excel at different things.
- Your budget: Super Quad builds can range from a few thousand to well over £15,000 for a top-spec build. Be honest about what you can afford and find a builder who works at that level.
- Reputation: Check their social media, ask in Super Quad Facebook groups, and look at previous builds. A good builder will have a portfolio of work they're proud to show off.
- Location: Transporting a quad for a build isn't cheap. Finding a builder within a reasonable distance can save you money and hassle.
- Aftercare: A good builder will stand behind their work. Ask about warranties, post-build support, and servicing options.
What to Expect from a Super Quad Build
A typical Super Quad build involves several stages. First is the donor quad — most builds start with a sports quad like a Yamaha YFZ450R, Honda TRX450R, or Kawasaki KFX450. The engine is then either rebuilt with high-compression pistons and hot cams, or swapped entirely for a larger displacement unit. The chassis may be stretched or reinforced, suspension is upgraded, and the bodywork is customised. Finally, the fuelling is sorted — usually with a programmable ECU or carburettor re-jetting.
Build times vary, but expect 4–12 weeks for a full build depending on the builder's workload and the complexity of the project.
Tips for a Successful Build
- Be clear about what you want: The more specific you are about power figures, intended use, and styling, the better the result.
- Don't skimp on the donor: A solid, straight donor quad makes for a much better base. Don't start with a wrecked frame and expect a great build.
- Trust your builder: If you've chosen a reputable builder, listen to their advice. They've done this many times before.
- Budget for extras: Builds almost always cost more than the initial quote. Set aside 10–15% for unexpected parts and upgrades.
