Owner report 11447626 · 2022-01-15 (January 15, 2022)
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 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.
