Sonic Springs rates for a 225# rider?

I'm about 225 fully geared and plan on doing some moderate distance, fully loaded touring with my Caribou and Maxia system. I plan on doing about 10% dirt...fire road type stuff. I also ride pretty agressively in the twisties. .95 springs were recommended for me, but that seems a little soft when I compare it to other rider setups on here...

Any input would be appreciated.

I'm about 220 without gear and I just ordered the 1.0s. I'll let you know how that works when they come in.

Cheers!

Rich is the expert but I had 1.0s on my Wee. Just the feel I preferred (pretty stiff). As I recall when I ordered them, the chart said .95 but Rich called informing me of a back order and said they could ship 1.0s right away and there was little difference.

The Vee springs in my first 5000 miles ride a lot like those 1.0s. Any Vee pilots out there experience front end nose dives and add aftermarket springs?

Anthony, I am a five pounds heavier and I really use my front brake alot. I was right on the cusp with the Sonic calculator, Rich advised me to go with the 1.0. and 15 weight oil,

They are going in this weekend.

Wow!!!!!!

OK Anthony, I did it. First, I had what I felt was all the tools including a front lift stand by PitBull, which I had to put a 2x6 under each side-the Wee is a tall bike. I have a rear stand. Then I just followed directions. The biggest pain and only swearing was from that little square fender nut on the left hand side. Other than that it was easy!!!

First while the Wee was never that bad, I am a bigger guy and weigh 230. I have a Superbrace and it helped. Lately, I had really noticed front end dive, especially with a full tank. Then upgrading to S/S brakelines continued the dive. Although the Superbrace helped, after reading here and the other place and talking with some spring folks, I decided to do the Sonic Springs thing.

Rich from Sonic gives a pretty comprehensive guide, along with what I read on the internet. IT also help to have a 15/16 socket and or wrench to do the top of the fork leg, you can get by with a cresent wrench. I really cleaned all the dust from when I cut the PVC. I didn't bother with Suzuki's little metal pipes. Although there certainly isn't a reason you couldn't find pipe like that in a good plumbing section!

I used 1.0 Sonic Springs & 15w as recommended. I took er out for a good ride including Sunday I-40 traffic which is wall to wall semi trucks do 80+.

ALSO I RAISED THE FORK LEGS 3/4 INCH AS RECOMMENDED BY RICH!

All I can say is I wish I have done this sooner. I can take my hands off the bars and steer with my knees at low speeds. Expansion joints were a little rough so I backed of the preload a touch. What a difference between stock and now. Especially with a fuill tank of gas. I stopped and put 4.2 gallons in. Then I went and did some panic stops-AWESOME! NO more dive.

The bike holds a line much better and I purposely put it in the turbulence of a semi on I-40 for about 4 miles. It does help. On ramps were a blast. Much smoother. I thought it might become too rigid, but It is a very comfortable ride and the bike doesn't wallow.

I wish you the best.

I have the Sonic 1.0s with 15W oil. Best singular improvement to the bike. I weigh 250, (down 27lbs and counting). Find the bike handles very well for me and a tremendous improvement over stock, especially front end diving under braking. I didn't raise the forks but did set the suspension sag as suggested in the Sonic website. Very impressed with the product and the customer service.

Safe riding
