My girlfriend had a K5 SVS that was lowered ( dog bones ) and it didnt feel any different to ride than my K1 SVS that wasnt.

If you arent comfortable with lowering the suspension then your other option is getting the seat re-sculptured and having some of the foam taken out of it.

Suzuki IIRC did a specific seat for the SV that was like this but I dont know if they do one for the Gladius.

Also you might find its not how much foam is in the seat but its more effected by the width of the seat itself.

Personally I'd try the seat re-sculpting first, rather than spending £800 on suspension parts.

How much lower did you need it to go for you to feel comfortable on it. As theres only so far you can go without it effecting the handling adversly
