2018 Lexmoto Monza 125 ZN 125 T-34 0.1L Petrol · OY18 FSO

The most recent MOT test on the 2018 LexMoto Monza 125 ZN occurred on 2025-09-01, following a failure in March 2025 that highlighted critical issues with the offside rear shock absorber’s serious fluid leak and insecure near-side handlebar grip, alongside major headlamp defects. While the vehicle passed the previous MOTs in 2023 and 2024, the pattern of recurring advisories—particularly the repeated near-side front shock absorber oil misting and fork seal failure—suggests a deteriorating suspension system. The failure in March 2025, however, was more severe, indicating either unresolved prior issues or accelerated wear, which could point to underlying structural or manufacturing defects in the shock absorbers. The advisories from 2025-03-12 and 2025-03-04 suggest the suspension components are nearing critical failure thresholds, warranting immediate attention to prevent further degradation or sudden suspension failure. The recorded mileage of 7,400 miles for a vehicle aged eight years represents an unusually low annual usage rate of approximately 925 miles per year, which is far below the typical wear rates for a motorcycle of this class. Such low mileage often correlates with periods of prolonged inactivity, particularly if the vehicle was stored without regular use, leading to potential issues such as corrosion from moisture ingress, fluid degradation from stagnation, and wear from static loads. For example, standing brakes may cause corrosion on brake discs or binding in calipers, while a stationary battery can suffer from deep discharge or electrolyte evaporation. Additionally, if the vehicle was left exposed to varying temperatures, the rubber components—such as seals, hoses, and suspension bushes—could degrade prematurely due to environmental exposure rather than mechanical stress. Given the recurring suspension advisories and the failure history, the buyer should prioritise a thorough inspection of the suspension system. On a test drive, listen for abnormal clunking or rattling from the front and rear forks, particularly when cornering or hitting bumps, as this may indicate failing shock absorbers or damaged coil springs. Check for uneven tyre wear patterns, which could signal misalignment or suspension imbalance, and inspect the tyres for signs of excessive dry rot or sidewall cracking, especially if the vehicle has been stored for extended periods. The near-side handlebar grip insecurity from the 2025 failure suggests a potential issue with the mounting hardware or grip itself; verify that the grip is firmly attached and that there is no play or looseness when gripping the handlebars. Additionally, the serious fluid leak from the offside rear shock absorber demands immediate replacement, as this could lead to hydraulic failure or catastrophic suspension collapse. The headlamp defects, while not critical to roadworthiness, should be addressed to ensure proper illumination and beam pattern, which is essential for visibility and compliance with emissions standards. For the buyer, given the vehicle’s age and low mileage, further practical checks should include verifying the condition of the 12V battery, as prolonged disuse can lead to reduced capacity or corrosion in terminals. Inspect the brake system for signs of corrosion on discs or warping, and check the brake fluid level and condition for any contamination or sludge, which could indicate age-related degradation. The brake calipers should be examined for binding or excessive play, as standing brakes can cause this issue. Fluid checks should also be performed on the cooling system, clutch, and gearbox, as these fluids degrade over time regardless of mileage. Lastly, a visual inspection of the exhaust system for leaks or corrosion is advisable, particularly if the vehicle has been stored in a damp environment. If the suspension components are beyond repair, the buyer should budget for a full suspension overhaul, as the current advisories and failure history suggest the system is nearing its operational limits.
