Fork Springs - which ones
« on: April 12, 2009, 08:47:00 pm »
I want to upgrade my front springs to address dive issues but do not want to sacrifice the ride. Which is the better set up? I weigh 160lbs with gear. Progressive springs with 15W oil, new 1.0 sonic springs with 15w or 1.1 sonic with 15w?

I weigh about 150 with gear on and went with the Sonic 1.1's. If you look around I think most here go with the Sonics. They really made my bike stable out on the highway. It's a great, cheap, easy upgrade. You won't be sorry.  '02 Connie  COG # 6662  Dallas, Tx

I put progressives with 15w in a few years back.  I even won some 1.1s at a rally and never got around to trying them.  I just had no issue with the way the progressives and 15w was working for me.  I am 180~  ----------------------------------  South Central Area Director  Email scad@cog-online.org    <p align="left">My Photos<br

I'm 5'6" @ 175lbs and put a set of Progressive springs on last year with 10w oil.  The only change I would make it put in 15w oil.  Otherwise I love the Progressive springs.    Hope this helps.  John

I had Progressive springs in my 03 and tried 10w and 15w oil.  By far the 15w oil was the best.    Here lately the wife and I was getting beat up pretty badly commuting back and forth to work.  She said to fix the bike or else....    Called Murph, I replaced the rear shock with the Fat Bastard Progressive model because we are both on the large side and I use the Concours as a pack mule.  The ride greatly improved but we were still getting beat up pretty bad.    I ordered the 1.2 Sonics, 15w oil and new fork seals from Murph, 3 hrs later it rides better than the wifes Cadillac now.  The wife is now happy, which makes me happy  ;p enough said.  Kurt & Sue Nordstrom  Spotsylvania, VA  COG 6049 & 6049A  VA & WV Assistant Area Directors
