Sounds like a bone stock new motor. If I remember the power drops like a rock up around 6500-7000RPM. Airbox and exhaust are very restrictive.Ive only had mine to 56 and Im a 180lbs. On a flat with little wind. At 6000rpm it goes 46. And to be clear the rpm bar has not passed the 6 on the rpms. If it had id call that 6200rpms
Earlier today I ran by the dealership and had them go over everything after 150 miles. Valve adjustment and oil change completed, I hopped back on and started home. Even pulling out of the parking lot, I could feel an improvement in performance. Rode about 60 miles this afternoon and then stopped to eat. When I got back on and started home, it felt still better. I'm sure some of it is attributable to me getting more comfortable and competent with the Grom, but it seems like it's loosening up. At the same time, it always felt very strong fresh from the dealer. Long story short, I wouldn't worry too much. Don't beat the crap out of it, but don't be too overly cautious. It seems like Honda aimed squarely at city riders and newbies, so they made something that doesn't need the kid gloves treatment. You're thinking about how you're riding, so chances are you'll be fine. Get out and have fun! Put some miles on it!Thx. Thats reassuring. Dont want to cruise 100 miles out at hi speed only to find I tore the engine up and find myself stranded.
