It happened twice in 2k KMs. When I ride normally on 6th gear, clutch itself releases for half of a second(maybe less) and re engages itself. But during this time engine revs as I hold gas. What is the issue here and what should I do?


Edit: it may not related to clutch, I’m not sure about it Bike: 2018 Honda CB250R

  • How many miles on the bike? Was the correct oil used during the last change? Not sure about your bike, but most bikes use a wet clutch which shares the engine oil. If the wrong oil is used, it can cause issues with the clutch. – Pᴀᴜʟsᴛᴇʀ2 Nov 16 '19 at 12:35
  • @Pᴀᴜʟsᴛᴇʀ2 I don’t know but 1k km ago I serviced my bike at authorized dealer of Honda. It’s 19k km at the moment – ggnoredo Nov 16 '19 at 12:36
  • I'd hope the dealer would be using the right oil, lol. Wouldn't it still be under warranty? If so, take it back to them ... however, it's probably hard to replicate the problem on demand. – Pᴀᴜʟsᴛᴇʀ2 Nov 16 '19 at 12:39

As mentioned, the gearbox fluid should at least be the correct grade and level etc from the dealer. I would take it back and ask them to check the clutch. Just tell them that after the service you've noticed the clutch slipping a few times. It may just be that they've taken too much slack out of the cable whilst adjusting it, this is just a 5 second job to put right. You can even check it yourself, just look up the lever adjustment recommendation in your manual.
