Currently, we support Visa, MasterCard, American Express, and Discover. Here are some problems you could be having:

• Make sure you have entered the correct card number, expiration date and security code without spaces or dashes.
• Verify that you are entering the exact billing address as it appears on your card statement. If your address and zip code do not match, the AVS (Address Verification System) will cause your payment to be declined. 
• If your payment is declined more than 3 times in 30 minutes, you will be locked out of our checkout process for 3 hours. This is a security measure to prevent people from using or verifying stolen credit cards. Please recheck your information and try again later.

If you have any other problems even after following this procedure, please contact help@ktm-parts.com and we will resolve your issue.
