A few workable options came up:

• Tank bag on the motorcycle: A padded tank bag can keep the camera protected and fairly quick to access once you stop. It can often hold a DSLR with lens attached, and some larger models may also help with extra gear. If it’s magnetic, just be mindful of where the magnets sit relative to the camera.

• Chest/front carry system: A camera harness or holster worn on the chest can give the fastest access. One answer specifically recommends a Cotton Carrier-style system because it locks the camera in place and reduces swinging. A toploader holster with a chest harness is a similar idea.

• Sling-style backpack: A sling/rotation backpack can be quicker than a standard daypack while still feeling secure. One answer also notes that some of these bags accept an optional tripod holder.

For the tripod, the most comfortable solution mentioned is a bag with a dedicated tripod holder/attachment, rather than carrying the tripod in its shoulder pouch.

For safety, the best balance is usually: ride with the camera secured in a bag, then access it when stopped.
