Hate to put a damper on things, but riding a motorcycle with something hung around ones neck might be considered a little risky by some!
You may not intend to have an accident, but other road users may not be so considerate
A lightweight compact combination of lens/body and a wrist strap would be my preferred setup. Don't rely on the strap and/or the D-rings to support the camera full time. They can/will fray or unwind under the continued movement of the bike (been there, done that). Hang on to the camera, with the strap being there just for insurance.
Have a safe trip
