What we do.

At Mean Machines, we build motorcycles with purpose.
From subtle upgrades to full custom builds, we work closely with you to create a bike that rides better, looks sharper, and feels truly yours.

Whether you’re chasing modern performance, classic style, or something wild and one-off — you’re involved in the process from concept to completion.

Quality parts. Honest advice. No shortcuts.

Fork Conversion & Front-end upgrades

One of the most popular upgrades we offer — and for good reason.

Modern fork conversions dramatically improve handling, braking, and rider confidence while giving your bike a more aggressive stance.

We specialise in fitting modern GSXR and similar front ends to classic and custom motorcycles, with options ranging from clean OEM-style finishes to fully custom, eye-catching setups.

​

Benefits:

  • Improved handling and braking performance

  • Modern suspension feel on classic bikes

  • Clean, safe, and engineered properly

  • OEM look or full custom styling

Custom Exhaust

Your bike should sound as good as it looks.

We design and fabricate custom exhaust systems to suit your bike’s style, performance goals, and riding needs. From subtle tone improvements to loud, raw statements — it’s built to match your vision.

Every system is made with fitment, performance and durability in mind.

​

Options include:

  • Custom headers and mufflers

  • Stainless steel / mild steel / titanium

  • Performance-focused or sound-focused builds

  • Unique one-off designs

Complete Re-Build

Bringing old bikes back to life is one of our passions.

Whether it’s a full nut-and-bolt restoration or a sympathetic rebuild that keeps the bike’s soul intact, we take care of every detail — mechanical, cosmetic, and functional.

We work with you to decide how original or

custom the final result should be.

Perfect for:

  • Classic motorcycles

  • Barn finds

  • Sentimental bikes

  • Period-correct or restomod builds

Wheel Conversion
&  Swing Arm Upgrades

Upgrading wheels and swingarms isn’t just about looks — it’s about performance, geometry, and safety.

We handle everything from modern wheel conversions to swingarm upgrades, ensuring correct alignment, spacing, and suspension setup.

Done properly, these upgrades transform how a bike rides.

Custom Fabrication & Prototyping

If it doesn’t exist — we’ll build it.

From brackets and mounts to subframes and one-off components, we fabricate custom parts in-house to suit your build perfectly.

This is ideal for custom projects where off-the-shelf parts just don’t cut it.

​

Fabrication services include:

  • Custom brackets and mounts

  • Subframes and tail sections

  • Swingarm modifications

  • One-off components and prototypes

Engine Re-build

Reliable power matters.

We offer engine rebuilds, upgrades, and mechanical work to ensure your bike runs strong, smooth, and dependable.

​

Whether it’s refreshing a tired motor or improving performance, we focus on longevity and rideability — not shortcuts.

Paint, Finish & Detailing

The final touches matter.

We work with trusted painters and finishers to deliver high-quality paint, coatings, and finishes that suit your build — from understated classics to bold custom looks.

Every detail is chosen to complement the bike as a whole.

Custom seat & Upholstery

Comfort and style should go hand in hand.

We design and fit custom seats that suit your riding position and the overall design of your motorcycle. Clean lines, quality materials, and proper fit — no mass-produced shortcuts.

Wiring & Electrical work

We design and tidy electrical systems to ensure everything works properly, safely, and looks professional. Whether it’s a full rewire or troubleshooting an existing mess, we’ll sort it properly.

​

Includes:

  • Full rewires

  • Simplified custom looms
