hey motomike. DO IT! too few people seem to be going out on enfields for the real fun long rides.
i have to say - best speeds were 45-55, i love those, that's pure enjoyment. 60-65 was good. i know i did 70 on the long canadian highways, quite a bit. it all vibrates but maybe i got used to it. i have no other bike to compare it to. above 40 i dont see anything in my rear mirrors anyways… but what i found crazier than the vibrations is the wind hitting me at the 65-70 speeds
so all together, yes i had the same feeling that 'i'm reaching the limits'
it's fun now, but i know i had to get used to it little by little. there were times when i didnt want to ride above 55mph that was the 'limits' for me then.
one thing what i was doing was: when riding with cars behind me going speeds i couldn't or didn't want to do - i waited for no traffic towards us or for part of road with big(ger) 'shoulder' of the road (is that the right term for it? i'm not native english speaker) - I slowed down, moved aside a bit and waved to the cars to pass me. they always appreciated it, waving me back or blinking. i didn't do it for them but for me. when i couldn't keep up with the traffic - i rather had nobody behind me than some local dude in a big truck, rushing somewhere
so - do your speeds. i mean, you cannot go faster than it lets you anyway
when you realize it's too much, hit the next exit and find some parallel road next to the highways. they are always more scenic anyways and i love that. and i had to do it on some highways when it became too windy too. even fully loaded bike, it was so light, i had some real scary moments because of that.
share with us, when you ride. i cannot wait when i take the green beast out again
