shock spacer

Post by haynesjones66 »

just noticed what looks like a slotted spacer above the shock. i assume with the nut removed and the bike lifted, this will slide out?

I wouldn't take the nut right off, loosen it up have a helper tip the bike up, get them to foot the side stand then pull the bike towards them & up, bike will pivot on the stand & lift the the rear off the ground... Have a practice before any hammer action... Once you get used to it & find the balance point its easy... No helper available then you'll have to suspend the bike with the rear off the ground...

Give the nut a whack with a persuader to give you the space to get the spacer out.

Lower the bike back down & tighten the nut back up...
Making up since 2007, sometimes it's true...Honest...

top man, thanks. i have a shorter blade front end so dropping the back would be a good idea

You might want to wait for a while until you're sure you're happy with it. The turn-in will be slower and you'll run out of ground clearance earlier.
It's not falling off, it's an upgrade opportunity.

the thing is, i have blade forks which are 30mm shorter than standard apparently, so with the spacer hiking up the rear by 20mm ish, that's a 50mm hike. so now there is only 10mm drop on the front. the reason i'm butchering my bike is to make it more ergonomic for my aging bones, so lower is better. it feels so much better now just to sit on as it seemed i was pitched forward a lot with the spacer in

RWU 'Blade forks give almost the same geometry as stock, not sure about the later USD ones. Remember that stock forks protrude about 45mm above the top yoke to mount the 'bars.

A 20mm rear spacer is still too much. 5mm at the back is enough.

i guess i'll hang on to the spacer for now, see how it handles. my spacer is only 6mm thick but that apparently translates to 20mm height at the tail end. or that's what i read on the american forum. anyway, i'll be a while working on this as i'm rather short on funds and spare time. all i've done so far is remove the subframe and mocked up the sv650 one, chopped it about a bit and currently making a steel plate to fit under the tank rear fixing for a front subframe mount

Nearly. A 6mm spacer made mine 19mm higher.
Measured vertically at the rear wheel spindle centre point.

I ran a 3 mm spacer with mine, it was just enough to make a difference and quicken the stering for road use without losing any stability. Don't be afraid to try some different ones, especially if you already have shortened forks you might not even need one. The last thing you want is a bike prone to tank slapping.

When I ran USD blade forks I had the 6mm spacer fitted, it only tankslapped twice in many thousands of miles, and both times I had provoked it, leant over with the throttle wide open running over catseyes.

Even then it stopped pretty quickly and re stabilised.

Enough to keep you awake, though.
