All Known Issues

Bespoke Avon Front Tyre Availability and Accelerated Edge Wear

ModerateSuspension & Chassis

The Super 3 uses bespoke 130/90R20 front tyres manufactured specifically by Avon (Speedmaster MKIII) mounted on 20-inch aerodisc wheels. The narrow vintage-inspired motorcycle footprint handles severe lateral cornering and braking forces without power steering or ABS. High-speed cornering or misaligned pull-rod steering geometry causes rapid shoulder scrubbing, and replacement tyres must be ordered through Morgan dealerships at significant expense.

Est. Repair Cost: £300–£650
Warning Signs:

Excessive scrubbing or feathered wear on front tyre tread shoulders, Front-end understeer and washed-out grip when pushing on in wet conditions, Tracking pull or wander on grooved and rutted UK road surfaces

What to Inspect:
  • Measure tread depth across both 130/90R20 Avon front tyres for uneven edge wear
  • Check pull-rod front suspension ball joints and tracking alignment for play
  • Inspect tyre sidewalls for stress cracks or scrubbing marks against wheel rims

Rear Drive Belt Tracking Noise and Sprocket Flange Rubbing

ModerateGearbox & Transmission

Final drive from the Mazda five-speed manual and rear bevel box to the single rear wheel is handled by a toothed Kevlar rubber belt. If swingarm alignment, eccentric hub tensioning, or wheel reinstallation following rear tyre changes is not calibrated accurately, the belt skews sideways against the sprocket flanges. This produces noticeable transmission screeching, accelerated tooth wear, and premature belt degradation.

Est. Repair Cost: £250–£600
Warning Signs:

High-pitched screeching or chirping sound from the rear swingarm on overrun, Noticeable bevel box and final drive gear whine at sustained cruising speeds, Visible rubber dust or chafing along the outer edges of the toothed drive belt

What to Inspect:
  • Inspect the final drive belt for edge fraying, stone gouges, or missing teeth
  • Verify central tracking of the drive belt between both sprocket guide flanges
  • Check service history for proper belt tension calibration after tyre replacement

Brake Pedal Feel and Linkage Interference

MinorBrakes

The Super 3's unassisted pedal box layout offers modest pedal feedback, and the linkage geometry can cause the driver's right footwear to catch on adjacent brackets when pivoting rapidly between the accelerator and brake pedal. While braking effort is adequate once firmly applied, the tight pedal spacing and spongy early travel demand acclimatisation on twisty UK B-roads and can compromise braking confidence in wet conditions.

Est. Repair Cost: £0–£120
Warning Signs:

Inconsistent or spongy brake pedal resistance on initial travel, Driver shoe or boot catching on pedal-box linkages during rapid transitions, Reduced braking confidence when pressing on along uneven UK asphalt

What to Inspect:
  • Test pedal firmness and ensure progressive resistance from the first inch of travel
  • Wear typical driving footwear to check whether shoes foul adjacent pedal linkages
  • Verify that brake fluid has been flushed and bled without trapped air

Buying Tips for 2025–2026 Morgan Super 3

  • Try the seating position before you commit: the seat is fixed, so shorter or taller buyers must rely on the adjustable pedal box and steering-column rake for a comfortable reach.
  • Press the brake pedal firmly during the test drive - reviewers note modest pedal feel and linkages that can catch the foot, so confirm braking is progressive and confident.
  • Check the optional moulded-plastic fly screen for warping or optical distortion; early screens were criticised for a distorted view and were revised for later production cars.
  • Confirm any outstanding safety recalls with a Morgan dealer or the GOV.UK/DVSA recall check before buying, particularly on 2023-build examples.
  • Inspect the bespoke Avon tyres for age-related cracking and check the drive belt for wear; replacements are specialist Morgan items, not off-the-shelf parts.
