Brand new motorcycle. Transmission is shifting hard and lots of whining and whirling noise coming from the engine block/Transmission/clutch. It's definitely a flawed design
I bought My 2023 Honda Grom at my local dealership on February 9th 2023 , brand new 0 miles. Around the 400 mile mark I noticed a "whining" sound after a long period of driving in 5th and in 4th gear. If you engine brake and down shift to 3rd or 2nd gear the noise goes away immediately. It only happens on occasion it doesn't do it all the time. I did purchase the 5 year warranty on motor and transmission. I did my oil changed at 600 miles with all OEM Honda parts and Fluids. The noise is still the same at 1000 miles. On May 10th 2023 I took …

I have 100 miles on my 2022 Honda Grom motorcycle. At around 50 miles it began making a noise it in 4th and 5th gear. I am worried that the noise in those gears may be causing other issues to my gearbox which can put me in danger. Neutral is hard to find and it sometimes slips into a false neutral that shows as “- -“. Once I was downshifting from 4rd to 3rd and it fell into the false neutral leaving me in a dangerous spot where I could not accelerate. I have contacted Honda but not heard back and I am going to see my dealer next Thursday to…

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
