Do I need new Monotubes?

I took the bike out for a little 100 mile spin this morning. First time on the bike since lumbar decompression. Did so with the surgeon's blessing. His advise when asked if it was ok to ride? "Don't fall off." Funny guy! During the ride I noticed that the expansion joints, small potholes, and general crappy Tucson road conditions produced a rougher ride than usual. When I arrived home I zip tied the forks and attempted to compress them with the front brake applied. 1 1/2" movement before bottoming out. I rolled the bike down hill and hammered the front brake. Identical result. I'm 260 lbs and the spacers used are 3/16" on both sides. It seems to me that there should be more travel. What say you, monotube users? TIA

I had mine go that way last year. Progressive replaced them. I assumed mine were from an original 'bad' batch as I think they were 1st generation (2012). Mine had 1 1/4" of travel.

Solo, your present suspension up front is OE, right? Your OE springs may be sacked-out; that is, deformed to where they are shorter than minimum spec length. Mine did that back in 2003 or 2004 with only 12,000 miles, which I hope is unusual and that all of the OE springs are not so poorly made. I used new OE refurbish parts, medium weight fluid from BullDog, and Progressive brand springs (no monotubs). I also deactivated the Anti Dive. Great ride that was still great at 70,000 when I had the original Traxxion Full Monty.

So, you have choices. MonoTubes get generally good reviews. You can do as I did. You can install linear springs with a refurbish. You can go big time with Tra$$ion. Any big improvement up front needs a good fresh or upgraded rear suspension. Similar choices there too.

In the mean time, to give your back a break from the rough bottoming, run front tire at Honda spec pressure and to H377 with the shorter tire life. Once you beef-up the front, you can nix that AD temporarily to see if you prefer that or not,

prs and all. I Neglected to mention I am running 1st generation Monotubes installed in 2012. My question remains...shouldn't I be seeing more than 1 1/2" of travel in the forks? Thanks.

I suspect that's what I may end up doing too, edmKC. Thanks

My 1st Gen. monotubes locked up after 12K miles. Really noticeable hitting the dip at the bottom of the driveway, they wouldn't compress much at all. I'm about same weight as you and had 1 spacer installed. Pulled them out, shipped back in original box, took exactly 3 weeks to get the replacements.
