Hi All, 

Basically progressive forks use springs that push back harder as they are compressed so they only work when the forks are being compressed, braking etc.

I have Progresive's cartridge monoshock up front. A vast improvement over stock fork springs.

Thanks for the feedback

From what I can tell the HD cartridge kit seems very similar to the Progressive kit.

+1. What Hilly said. I have these on my 2012 ultra. Way better than stock.

So by that do you mean Ohlins?

After doing a 1285km over two days down through the Snowny high country its time for the upgrade.

Thanks Leachy

leachy , I would look up Shock Treatment  ( do a google ) .

Thanks for that

After riding jap bikes for years then getting a nightrain I couldn't believe how bad the suspension was. 

Well I am happy with the heavy duty ones but I weigh a bit more than you do. (not a great deal though)
If you regularly take your missus for a ride then maybe the heavy duty ones are for you too. However if most of your riding is just you then prolly the regular ones.
I have heard of blokes getting the heavy duty ones only to find out they are too firm/harsh then going to the standards and being much happier with them.
Both Rollies Speed shop(who I bought them from) and a local indy dealer recommended the heavy duties.
Also keep in mind the shocks give a bit after a thousand klms or so.
Mine are still set at close to the minimum setting.
I have not lowered mine at all as there are some bumpy roads round here.

Hi Lucky

I did my rear shocks first, put in 13" Progressive 490's made a huge difference and highlighted how crap the front stock suspension is. I was looking at the Progressive cartridge kit but was worried it was going to be too hard after reading a few different comments, i weigh about 83kg and generally it just me on the bike. I was also looking at Ohlins but a bit expensive. Im not trying to turn this into a sports bike, I still have one of those just something that actually absorbs the shitty road surfaces.
