You don't need a speedo for the MOT. You might need a speedo for your insurance. I'm no legal Beagle, but check the road vehicle regulations or whatever they are called. To be fair, I rode a bike around for 3 or 4 years without one before shifting insurers, who got a bit shirty. Just trying to help.Yes.
To start with speedo app on phone will do, just want to get it mot’d and insured so I can take it out for a short run or two and make sure it runs ok.
