V2 Raising and Lowering Linkage

I have the proof of concept worked out, installed, and tested. The range is +/- 1.5" (+/- 38.1 mm) measured at the rear wheel.

Now the production sizes need to be determined. 1" lowering and 1" raising has been requested and will be produced.

Are there any other sizes that are needed/desired.

Rick,
You are a true asset to Vstrom owners. I wasn't looking for lowering links, but I would buy one from you. When the 1" lowering links are ready, please let the board know, and I will purchase a set. Thanks!

Good one Rick.

Well I'm certainly interested but have a few questions.

I don't know if I want to go more than 25mm rise at rear UNLESS I can raise the front around 10mm.
Do you have an opinion on this?

Looks to me like we could lower the forks 10mm through the fork clamps but do you think a sleeve of fork diameter may be required to get a safer and more secure purchase when retightening the upper fork clamp bolts

I know raising only the rear may be fine with a pillion and luggage on board to compress it but what about when riding solo (which is 90% of the time)

many thanks in anticipation, Steve

The discussion elsewhere about needing to raise the bike to accommodate a skid pan got me thinking about how to raise the front. of the bike.

In the sixties and seventies when the chopper craze was going strong people could buy extensions for their existing telescopic forks. Basically, you unscrewed the fork tube cap, screwed in a an extension, and then put the original cap on the top of the extension.

I just did a search an they are still being made for cruisers. XChoppers Honda VTX Chopper Parts for 1300 and 1800 VTX Motorcycles

Something similar, but less extreme could be done for the V2. With a modest increase in length (~1"), it might be possible to put the joint inside the upper triple tree clamp, but I don't know how important that would be.

Theoretically I "could" make these with my equipment, but I'm not really set up for it. It would be much less CNC and much more manual machining.

I'll think about it some more and make some inquiries.

FWIW - I would like to improve ground clearance with a suspension lift, but have the same concern with raising the rear without doing the front. I would think that the quicker steering resulting from a rear only raise, which would be good on pavement, would likely be a problem in the dirt, particularly in soft sand etc. - making the front end to twitchy?

I for one would be very interested in a kit of some sort that allows both front and rear to be raised. Fork spring rate increase would help a bit to though (which I happen to need anyhow)

No longer a Vstrom Owner - fantastic bike! Now sporting a KTM 990 Adventure

We had some relatively nice weather here for a few hours yesterday so I had a chance to test the 1.125" raising linkage on the Vee2.

I am a very cautious person when it comes to things like this, but there were no issues what-so-ever. I couldn't actually tell any difference in handling performance on the highway or in tight twisty turns.

The center stand and side stand both still work. With the bike on the center stand the rear tire makes contact with the surface, but can be rotated by hand. While on the side stand the bike leans over further, but not so much that I was ever worried about it.

I should get 1" lowering link tested this week.

Expect both to be available on our web page this week.

These were called slugs and they were by and large deathtraps. I'm old enough to remember them well. The had a tendency to unscrew, which made for some interesting handling when one or both of the forks suddenly became two piece things held only by the lower trees. The other problem that came up sometimes was that they broke right where they were threaded. Again, interesting handling resulted. OTOH, these were on Harleys, which didn't clamp the top of the fork tube with the top tree; just the lower tree had actual clamping force.

If you're able to machine them so that the joint was still held by the upper tree they might, please hear the might, be durable. If it were me, I still wouldn't use them.

Of course, what I'd do isn't necessarily the golden rule for what anybody else would do. I'm just one data point, but in this case, I've been there, done that and have the t-shirt.

Spunky,

Good retrospect on the dangers of 60's era choppers with their 6", 8", and longer fork tube extensions.

I doubt increasing the Vee2's forks 10 mm would have the same evil effects since the extender would be held within the upper triple clamp, but it is probably an academic discussion. Unlike the fork tubes of the 60's, the Vee2's fork tubes have adjustment devices built into them. This probably makes using a fork tube extender moot.

I'm really not sure of your claim that you can remember the sixties though. After all as they say "if you can remember the sixties you probably weren't really there."

,,,and if you go chasing rabbits....

I was just thinking today about raising the rear an inch or so, and then I saw this. I recently bought a wrecked Wee, hence the moniker, and am doing the DR650 fork inner tube "up" grade, though I will only add 1-3/4" travel and only ~2" ride height to the front. Hopefully 1-1/8" in the rear will bring me adequate balance. I will likely order a set as soon as this thing gets its turn on the lift. I still have to go out to a county road nearby and see if I can find some more of its parts.
