Lowering kit

Has anyone installed a lowering kit on their bikes? And if so, did it change the handling? KTM says that it doesn’t change, but my dealer is strongly recommending against it. They told me it would drastically alter the handling.

If anyone has one installed and could give feedback I would appreciate it as I can’t find anything online.

Thanks.

The only lowering kits I've seen are to reduce the seat height by 25mm. Don't really know if that's worth the $300 they are charging for it. Least it wont make any changes to ride dynamics. https://www.ktm-parts.com/64112955044.html

I have installed the lowering kit and I'm very happy with the result. I don't trust the lower seat hight because I think it will make me spread my legs more there by eliminating the gain it provides in the first place and also will make the handlebars taller relative to the seat which I'm not interested in. I still didn't received the shorter side stand, three months after.

You have a link/name to the lowering kit that you put on your bike? How much did it bring it down by and have you noticed any major differences in controlling the bike?

The link is the same as SirDuke provided (by lower seat hight I ment the "KTM Ergo Low Seat" https://www.ktm-parts.com/64107140000.html). I have never made the measurment of how much did it bring it down but 25mm seems right to me. I'm a 167cm tall and I like to reach the floor comftroubly with both my feets. Also The tallest bike up until now for me was 810mm and It feels more natural for me to lean the bike over on a shorter bike. There is also a little bit less forward and backward movement which is to be expected when lowering a bike CG. I love the explenation of changing the bike geometry in the following link https://www.cycleworld.com/sport-rid...eometry#page-4.

Oh I thought you had managed to source an actual aftermarket fork/spring kit. Unless you're planning on tracking the bike I don't think a simple seat adjustment would have any serious impacts on riding dynamics.

I have talked with Matris about their front and rear shock for the 790 and they say they have shorter eylet joint (about 15 mm less) for the rear shock, obviosly you don't need anything for the front.

if you lower the front and rear the same amount the bikes handling will be almost unchanged some kits have shorter springs which lowers you bike but does reduce suspension travel

on the 390 the kit came with short fork springs and different rear shock mount and shorter side stand, the 790 kit does not seem to say exactly what you get

what you do lose is ground clearance

Joy is riding your bike to it's limit

You lose front forks travel distance in the KTM kit.
