The first thing is :
70 mph is the upper cruising limit. The factory gearing is even more than 80 mph.
I put the 16 tooth front sprocket on after break-in . Also put on the DNA Air filter and air entry cone.
This week I went from middle TN. (USA) over to east TN. for a day ride (150 mile) just to enjoy the last day before a cold front sets in. So , middle TN. is basically flat country with hills. East TN. is long up and down main roads and low speed twistys on the back roads.
On the "Hill Country" part the Meteor will run 70 mph up and/or down with no problem.
But
On the long up-hill grades the Meteor needs to drop into 4th to hold 60mph , but doesn't have to be full throttle . Think of 18 wheel trucks doing 45mph going up-hill. Remember that 4th gear will run up to and past 70mph on flat ground (16 tooth F sprocket). Think of the RE-350 as being a 4 speed with an "Over-Drive". So , yea - you have to come out of "Over-Drive " to go up serious inclines. I drop into 4th at the bottom of those long-up-hill grades to keep from a mid way down shift.
I bought mine in June 2022 and am coming up on 6000 miles very soon , about 1000 miles a month.
I rode over to "The Tail of the Dragon" this summer (250 mile - one way) and spent a week ridding with a buddy on a Suzuki 650 S-40. The RE 350 kept up just fine. The only time I felt "Under-Powered" was on those long uphill main roads , and even then ... I knew that I was wide open in 4th gear but my buddy never knew it , all he knew was I was keeping up just fine and getting "WAY WAY better fuel eco. than he was !
