Description
The MED Verto flywheel is CNC turned from EN8 steel billet, after which we profile mill large slots through the flywheel on the outer edge for extra weight saving.
The flywheel weighs approximately 2.2kg less than the standard unit at just 3.55kg.
If you require a complete balanced assembly with the clutch plate, competition clutch cover and centre boss, see the MED Verto St1 or MED Verto St2.
This makes an excellent upgrade over the standard Verto flywheel, for fast road or competition.

Ultra Light Verto Steel Flywheel 3.55kg
Complete assembly 8.5kg
Recommended usage
Upgrading to an MED steel flywheel not only saves weight, but also gives a more durable surface face on which to grip the clutch plate. The lighter the flywheel, the faster the engine will be able to increase/decrease RPM, making it more free-revving and responsive to throttle input.
MED Verto Ultra Light is our preferred option for performance road cars. The flywheel itself weighs approximately 2kg less than the standard type, while the later Verto clutch arm design gives an easier clutch pedal than the early diaphragm type. MED Verto flywheels are also suitable for light competition usage.
This flywheel will suit all transverse A-Series engines (Mini/Metro) with a Verto clutch setup. Please note - this will not suit fuel-injected Rover Minis. See the MED SPi Flywheel or MED MPi Flywheel for these cars.
Alternative options
If you prefer the original diaphragm-type clutch setup, it is possible to retrofit a Verto-equipped Mini with an MED Heavy Duty Clutch Operating Kit.
You will need to remove the slave cylinder mounting bracket and use a different clutch hose/flywheel bolt, but everything else is a direct swap. The advantage in swapping to the original design is reduced overall mass of the clutch/flywheel assembly, which is ideal for competition.
The downside is a heavier clutch pedal, hence why we recommend the Verto system for regular road use.
Frequently Asked Questions
Which classic Minis does this flywheel suit?
This flywheel will suit all transverse A-Series engines (Mini/Metro) with a Verto-style clutch setup and pre-engaged starter motor, which was introduced in the early 1980s. This can also be retrofitted to an earlier car by changing the clutch mechanism and starter motor. Please note - this will not suit fuel-injected Rover Minis, but we make a version specifically for SPi and MPi Minis.
What is the advantage of this flywheel?
Upgrading to an MED steel flywheel not only saves weight, but also gives a more durable surface face on which to grip the clutch plate. The lighter the flywheel, the faster the engine will be able to increase/decrease RPM, making it more free-revving and responsive to throttle input.
Will this flywheel increase the power of my Mini?
No, changing the flywheel has no effect on the power output of the A-Series engine, however it does increase responsiveness and acceleration by reducing rotational inertia. Reducing weight from the flywheel in particular has a far greater impact on acceleration of the Mini than weight loss elsewhere, so is highly recommended for all performance Minis.
Which starter motor do I need to use?
This flywheel has 129 teeth on the ring gear and is designed for pre-engaged Mini starter motors only, either standard-spec or aftermarket high-torque units. Standard pre-engaged starter motors can be identified by an in-built solenoid, and were fitted from the advent of the Verto-style flywheel in the early 1980s. Be careful with budget-grade replacement starter motors, as flex in the starter motor bendix can damage the ring gear teeth. We would recommend using either an MED-5200-HTP or MED-5240-MP starter motor if you're looking for an upgrade.
How does this compare to a standard Mini flywheel?
These are machined from certified EN8 steel billets compared to the cast iron originals. As a result, we can reduce the overall weight far more than is safely achievable on a standard flywheel, which are brittle in comparison. The ring gear teeth are also machined into the steel, then specially heat treated, for much improved longevity.
Is this flywheel balanced?
No, as the flywheel will need to be bolted to a Verto-style clutch cover and centre boss, then balanced as an assembly. It's not possible to balance the flywheel as a standalone item. If you would like this to be balanced, we offer complete kits that are ready to bolt on, complete with new cover and friction plate.
Which diameter clutch plate is this designed for?
Either 180mm or 190mm diameter plates will work. Our range of performance plates are all 180mm in diameter.
Will this bolt on to a standard clutch cover?
Yes, either a standard clutch cover, or preferably one of our upgraded versions.
