I am very sensitive to handlebar vibrations, but I've learned over a lot of bikes and vibration reports that people resonate differently. What one rider considers unnacceptablle another rider may consider to be just fine, and vice versa. I also think riders grow accustomed to things like vibes over time, and they don't seem as bad after a while.
I have done considerable back to back testing of 2 GSA LCs I've had with 3 different Gen II S10s that I've had. My observations:
- During leisurely riding below 50mph, the GSA-LC can be very smooth, more or less as smooth as the S10.
- Under hard acceleration the GSA-LC vibrates much more than the S10.
- Under heavy load, for example 2 up steep grade, the GSA-LC vibrates much more than the S10.
- The GSA-LC vibrates at idle, the S10 is definitely smoother there.
- By far the worst vibes from the GSA-LC are above 65MPH+. Basically freeway speed and beyond. I hate it. S10 at similar speeds is much smoother.
After an hour of spirited riding on the GSA-LC, my hands are numb for several hours. After a day on the S10, I'm not numb.
This comparison is pure stock GSA-LC(s) against pure stock S10 Gen II(s) wearing lightly padded leather riding gloves.
