Front fork raise - step by step report with pics

required tools: 10 mm wrench, vernier caliper


while on center stand, support the bike with a jack or a suitable log so the front tyre does not touch the ground


measure the initial stock setting, so later you can set it back if needed


maximum possible raise is about 1.5 inch


first loosen the lower screws of the fork


secondly loosen the upper fastening screw
set both forks to EXACTLY the same height, be careful to avoid hitting the handlebar with the spring preload setting screw


secure the fork fastening screws in reverse order

ensure the new setting does not obstruct the free travel of the fork

I tried to lower the bike as most of the folks do here who have 30" or even shorter inseam like I do. I do not have lowering links yet, so I started with the front as that does not have negative impact on the bike's behaviour.
And I thought if I put a report here it can be useful for someone else who also fight with our lovely monster. To be honest it made not a big difference in "flat footing" but the curving behaviour become better. So my next project will be the lowering link. Of course with a report such as this one.

What makes you think it doesn't impact the bikes behavior? Maybe not totally negative, but you just changed the entire geometry (rack & trail) of the front end of your bike. I'm a new strom owner myself, but I've got lots of experience on the track and with full fledge sportbikes. Dropping the front like you did quickens the steering and tends to make the bike more unstable at speed. If you get too far, you totally loose the feel of the front in the truns.

Now, granted the strom has no where near the aggressiveness of a rake as a sportbike, so you probbably won't see too much, but I just didn't want to you to think or give others a false impression that what you changed did not affect the bike in some shape or form. Exactly how much is the true question. 1.5" seems like a lot when I could tell 5mm on some of my bikes when I changed the fork height.

Nice write up though on how you did it.

I would think lowering the front a bit would help the cornering considerably.. I come from a sportbike/track background as well, and while the Strom does pretty good 'for what it is' in the corners, i found myself plowing the front end mid corner-exit, when opening the throttle.
1.5" seems like a ton, but i'd guess that the strom is much less sensitive to the adjustment than pure sportbikes.

I agree with you that I have changed the geometry. I did not stated I haven't. If it seems I gave false impressions other, I am sorry, didn't want to.

Well maybe I was not enough clear, but check it again I wrote "maximum possible raise is about 1.5 inch". I wanted to say this is the allowed maximum without hitting the triangle by the lower part of the fork when it moves up.
I did not raise it so much, only by 15 mm (0.59") and maybe because I am not so experienced as you are I do not feel too much difference in the behaviour.

I felt something similar before (a bit less) but also after (a bit more) the raise. Anyhow maybe my bad english will not allow to express well but that is a BIG difference in curving behaviour compared to my prevoius bike the VF 500 (Interceptor in the US). When I went into a curve with the Honda I usually released a bit the throttle (engine brake), the bike fell down without any help or body movement. From the middle of the curve slowly opening the throttle the bike started to stand up, also without any other trick. When I only cruised in a curve (no brake, no acceleration) the bike just followed the line. This kind of curving behavoiur I have never experienced on the DL neither before nor after the raise of the forks. It curves absolutely neutral wether you brake, cruise or accelerate. For me it is a bit (a LOT) strange and need to get used to it. I always need to play with it to keep her on the line because I always wait for the fall down or stand up. Well after some (hundreds or thousands of) miles it will become the natural behaviour and the other will be strange.
I have never been educated by any track-expert biker, so I wrote it surely not workmanlike but these are my observations, after 15 years and some thousands of miles of riding a few machines.

Supposedly, dropping the front 1/2 in makes it more stable in a crosswind and quickens the turning. I dunno, but, it's a "common" modification to get the V railing the corners better and felling like it's planted better on the slabs.

It's on here somewhere.

Wow! Dropped the front 3/4" of a inch after lowering the rear 1 1/4" of a inch. What a amazing difference on the road. Wow its like a whole new bike. I"m glad I did it and strongly suggest everyone else who uses lowering links balance out the front.
