My question involves a traffic ticket from the state of: WA

I was driving in a 25mph zone, going with the flow of traffic, when I was pulled over by a motorcycle police officer. The officer told me that he pulled me over because I was speeding and told me speed was 27mph, +2mph above limit, and no other reason. On the ticket he issued me, speed wasn't included. The only note was "inattention to driving."
I've never heard of this before. I would like to know if this is something I can take action against. Personally it sounds pretty ridiculous to me, but I suppose I could be mistaken. I wasn't the only person on the road and not the only one who got pulled over for that matter.

Thank you in advance for your time and help.
