Welcome to the SpyderHood
:congrats: on switching to 3 wheel'n & :welcome: to the SpyderHood. This is one of the best sites for any information Spyder related :firstplace:
Seems you've already done some research on your oversteering issue. I know the RS/GS & RT are 2 very different machines when it comes to handling, but as you mentioned, wind buffeting has a lot to do with twitchy steering.
This morning, on my way into work, (19F) I rode for a few miles with the shield on my RT-S all the way down, & I swear, especially with my full helmet, I felt like a bobble head. With my head be'n blown around, that energy transfers to my upper body & ultimately down my arms & to my hands. Even with using a light grip, I was constantly overcorrecting just try'n to keep it str8. Mind you, my RT-S seems most comfortable on the highway at 80 mph, so this was not
fun at all. After about 5 miles & getting exhausted, I put my shield back up to
1/2 way, and WALAH!!!! a totally different ryde. So smooth, so comfortable ...... Even at 80+
So yeah, try'n to divert the wind from making you into a bobble head will help,
along with a light grip. Having your dealer check for toe-In to make sure that's not an issue can't hurt either.
Other members have upgraded the front shocks on the RS/GS model, some with Elkas and other After Market sets, & others seem to love the handling
they get from putting the 2010RT shocks on the RS/GS.
Sorry I can't offer more advice for you, but I'm sure some of the more
experienced members of the forum will chime in & provide some additional
suggestions.:2thumbs: Oh yeah, along with the lighter grip, make sure when going into a turn, lower your center of gravity & lean
INTO the turn. My 1st ryde was a 120 road trip home, most all on the
expressway at 60+ & I didn't know this little secret back then. Needless to say, I learned real quick! :roflblack:
Give it some time & practice & you'll be love'n it like the rest of us :thumbup:
