Hello, I have a Yamaha yzf r125 16 plate. Last last couple of days I’ve noticed when I’m riding the bike will lose power for a split second and then goes back to normal. No warning lights are the dash. It’s as if the brakes go on and then released for a millisecond. It’s being getting slightly worse the more a ride it. It mainly happens when I hit a bump but It has happened randomly. My dash remains normal when this happens which make me thinks it’s not that, that needs charging. I’m not very knowledgable when it comes to this stuff so if someone could give me a rough idea of what this could be I’d appreciate it! Many thanks
