Adventure Power Sports has been doing "non servicable" V Strom shocks for years...including the newer 2014up 1000 type which looks very similar to the Tenere shock (non ES)
I'll be sending my Strom suspension in soon.....Tenere to follow after that.
$800 for a completely modded suspension front & rear is very reasonable. Ive ridden a friends Strom before & after the mods were done.... Transformed the bike.
