Welcome to RidersCalc (the “Website”). By accessing and using this Website, you agree to comply with and be bound by the following terms, conditions, and policies. If you disagree with any part of these terms, please do not use our Website.
Affiliate Disclosure
RidersCalc is an independent, user-supported project. To keep our motorcycle ergonomics calculators free to use, we participate in various affiliate marketing programs.
- Amazon Associates Program: RidersCalc is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, I earn from qualifying purchases.
- Other Affiliates: We may also participate in affiliate programs with RevZilla or other motorcycle gear retailers.
What does this mean for you? When you click on a link to a merchant (like lowering kits, seats, or boots) and make a purchase, we may receive a small commission at absolutely no extra cost to you. We only link to products and services that we believe add value to our fellow riders.
Terms of Use
The tools, calculators, and content provided on RidersCalc are for informational and educational purposes only.
- Accuracy is Not Guaranteed: While we strive to keep our motorcycle database (seat heights, weights, peg locations) as accurate as possible by sourcing data from manufacturers and expert reviews, specifications can change by model year, region, or suspension settings.
- Ergonomics are Subjective: The “Knee Angle” and “Ground Reach” estimations are based on mathematical models using average human proportions. Your actual inseam, riding boots, weight, and suspension sag will affect how a motorcycle actually fits you in real life.
- Assumption of Risk: Motorcycling is inherently dangerous. You should always sit on a motorcycle in person and consult with a certified dealership or mechanic before modifying your bike’s suspension or ergonomics. RidersCalc assumes no liability for any injuries, damages, or financial losses resulting from the use of the information provided on this Website.
Privacy Policy
We respect your privacy and are committed to protecting it.
- Information We Collect: We do not require you to create an account or provide personal information to use the calculators. We do not collect or store your height or inseam data on our servers; these calculations happen locally in your web browser.
- Cookies & Analytics: We may use standard third-party tools (like Google Analytics) to understand how visitors use our site. These tools use “cookies” to collect non-personally identifiable information, such as your IP address, browser type, and the pages you visit. This helps us improve the Website.
- Third-Party Links: Our Website contains links to external sites (like Amazon). Once you leave our Website, we are not responsible for the privacy practices of those other sites. We encourage you to read their privacy policies.
