Great upgrade

Installed these springs into my 1983 BMW R100 (along with a pair of 412 series rear shocks) and suddenly cornering is confident, road imperfections are smoothed out, diving on braking is drastically reduced. All-in-all, a great upgrade for the money.

once again

I recondition 5-10 older bikes each year, more often than not i'll throw a set of Progressive fork springs in. They restore ride height and eliminates that squishy, bouncy, 30 year old ride.

VTX1300 Great improvement!

With the stock springs I would get a slight wobble when no handed between 30 and 40 mph. Installing these springs complete removed this problem! When pulling my trailer, the wobble was severe,even with my hands on. That also has gone away. Just got back from a 600 mile trip, and I am extatic with these springs!

Refreshed Front End

Replaced mushy springs on 84' V65 Magna. Springs are a great addition to older bike. Feel good and much more stable ride. No issues with install. Used new PVC for each spacer. Instructions were clear and had all required details. Very Nice.

Awesome Suspension for a Great Price

These springs from Progressive (11-1126) are a huge upgrade from stock on my '02 Honda Spirit Shadow VT1100C. Nose diving on deceleration or stopping is no longer an issue. The directions included as well as following the Honda manual make this swap a breeze. I installed them with new spacers, 15W fork oil and new seals, and I love them already. I highly recommend these springs for anyone looking to improve their ride and handling.

It really does fit.

First off, this product #58967 WILL fit the 2007 Honda Aero. Despite what the fitment says. The original springs are 14.5" in length and the Progressive springs are 18". The difference comes into play with the spacer. The original spacer is about 11" long and the one that you put back into the forks is only 3.20" for the 2007 Honda Aero. I would highley recommend this upgrade to your front suspension. Also, you might want to get a set of progressive rear shocks. Just a suggestion.
