Step-by-Step Tutorial

Learn how to use the key blank dimensions calculator for professional results

1

Select Key Type

Choose the appropriate key type based on the lock system. Different key types have specific dimensional requirements and cutting patterns.

2

Choose Motorcycle Brand

Select the motorcycle manufacturer as each brand has specific key specifications and dimensional standards that affect the final key blank design.

3

Set Number of Cuts

Specify the total number of cuts required. This determines the minimum blade length needed to accommodate all cuts with proper spacing.

4

Select Lock Type

Choose the specific lock application as different locks may have varying dimensional constraints and insertion requirements.

5

Choose Application

Select the intended use case to apply appropriate dimensional standards for OEM replacement, aftermarket, or custom applications.

Frequently Asked Questions

Common questions about key blank dimensions and specifications

What are standard key blank dimensions?

Standard motorcycle key blanks typically measure 65-75mm in length, 8-12mm in width, and 2.0-2.5mm in thickness, with variations based on manufacturer specifications and key type.

How do I determine the correct key blank size?

Key blank size is determined by the lock cylinder specifications, key type, number of cuts required, and manufacturing tolerances. Our calculator considers all these factors for optimal sizing.

What is the difference between bow and blade dimensions?

The bow is the handle portion of the key, while the blade is the cutting portion that enters the lock. Each has specific dimensional requirements for proper function and ergonomics.

Can I customize key blank dimensions?

Yes, within manufacturing constraints and lock compatibility requirements. Custom dimensions may be needed for special applications or unique lock systems.
