Shock & Spring Updgrade
After listening to others, I decided to upgrade the suspension
of my 95 Nighthawk 750:
- Rear Shocks & Springs: I mail ordered the
Progressive shocks (PS1202B) and springs (PS1367C) from
Competition Accessories for $164.90, plus $10 shipping. When they
arrived, I discovered that they are shipped in seperate boxes,
which means you have to put the springs on the shocks. I, like
most people, do not posess superhuman strength, nor do I have a
spring compression tool. I found a local independant shop who
assembled them for $10.00. Following this, I put them on the bike.
You won't need item by item assembly instructions for this. It's
pretty basic. Just make sure you get the right torque values. The
upper and lower shock bolts are 25 ft/lb, and the rear panel
screws are 9 ft/lb. Once I hit the road--What a difference! Bumps
don't jar as badly, and there's less up and down movement in the
rear. It's like the difference between a BMW Z3 and a old Ford
Ranger (Yes, my wife lets me drive her Z once in a while).
- Update on part numbers from J. Finch I think I have
solved a mystery about these progressive shocks. When I called
CompAcc, the rep. recommended the 412 series which is fully
assembled. Priced at $199. The Dennis Kirk catalog describes
the 12 series as identical to the 412, but with shocks and
springs sold separately. The l2 series was formerly rhe 1200
series and the 412 was the 4000 series. CompAcc quoted me the
same price for the 12 series that you paid. So it appears you
made out OK as the 412's are $34 more than yours. I think I'll
get the 412 and avoid looking for an assembler. Incidently, a
dealer quoted me about $50 more than CA for the 12's with
assembling about $30.
- My Comment: The choice is your's. If you have a shop
around who can put the shocks and springs together cheaply,
then you can save some bucks. It's nice to know you can order
them either apart or assembled.
- Front fork springs- After 6 months of riding, I can
recommend the Progressive front fork springs too! I'm not an
engineer, so I won't bore you with suspension buzz words like
"rebound", "compression", "damping", "oscillation", and other
similar words that the motorcycle testers throw around. Hell, I
don't even know what most of them mean. I will just try to explain
in layman's terms what it feels like: "A whole lot better". The
bike is much better at handling all of the road's imperfections.
You still know that you've hit a bump or a hole, but the bike just
seems to deal with it more quickly, and you feel it less. There's
less up and down motion on the front forks, especially while
braking. There's still some "fork dive", but a lot less than
before. Overall, the combined effect of the Rear Shocks/Springs
and the front fork springs is well worth the money.
- For those of you who do a lot of "two up" riding, or carry a
big load, Progressive also sells a "heavy-duty" version of the
above shocks & springs.
