Motorcycle manufacturers often electronically limit the top speed of superbikes and scooters for safety and regulation compliance. However, experienced riders looking to use closed tracks or competitions may benefit from disabling the vmax aufhebung. This guide covers legally bypassing your bike’s speed limiter yourself to reveal its maximum velocity capabilities.
What Is a Speed Limiter on a Motorcycle?
A vmax aufhebung or speed limiter on motorcycles and high powered electric scooters refers to programmed software built into the ECU (engine control unit) computer module. It electronically prevents acceleration beyond a factory set maximum speed, which is often generously above public road laws anyways. Limits typically range from 124-155 mph.
Benefits of Professionally Removing Limiter
There are select cases where disabling the vmax becomes necessary:
- Closed Track Racing – Reveal true straight-line potential
- Competition Top Speed Runs – Unlock every ounce of speed
- Diagnostic Capability – Test components under full load
- Smoother High-Speed Gear Changes – Prevent abrupt deceleration
Of course this should only be done legally on closed courses with appropriate safety gear. Professional shops have the tuning tools and dyno equipment necessary to fine tune post-removal performance.
Is Self-Removing the Limiter Illlegal?
While some regions prohibit tampering with factory emissions settings, in most areas it is legal to bypass vmax aufhebung speed limiters yourself on bikes intended solely for closed circuit uses. Any public road riding with disabled limiters can result in violations and penalties. Always confirm regional laws first.
How to Bypass Speed Limiter at Home:
With laws confirmed, experienced riders able to access custom ECU tuning software and cables can carefully disable limiters through these steps:
- Gain Access to ECU Connection Port – Varies by model
- Connect Tuning Laptop and Data Cable to Bike’s ECU
- Backup Original Performance Mapping Settings
- Adjust Target Top Speed Parameter to Max Value
- Write New ECU Tuning File with Limiter Removed
- Clear All Codes and Confirm Changes Took Effect
This keeps fuelling, timing and all other parameters stock. An unrestricted top speed parameter is the only change required to maximize velocity cap while maintaining ride-ability.
Risks to Consider
While accessing more of your bike’s performance potential appeals to many owners, self-removing factory speed limiters has some risks:
- ECU Damage if Tuning Process Interupted
- Irreversible ECU Corruption Without Backups
- Increased Engine Strain at High Speeds
- Catastrophic Failure if Components Exceed Limits
- Voided Warranties on Powertrain Components
Without professional dyno tuning, it takes trial and error to settle rev and speed safety thresholds. Extensive mechanical experience working on sportbikes is highly recommended before attempting.
The Safest Approach
Ultimately, the most prudent option is having your motorcycle’s vmax aufhebung removal performed by a reputable speed shop with advanced tuning capabilities. They optimize overall performance to handle the bike’s new unrestrained top speed while providing professional safety oversight. Consider your riding experience carefully before exceeding factory limits on your own through ECU tuning. In the right hands however, disabling the speed limiter yourself grants exclusive access to your bike’s maximum performance potential.
