Rear shock upgrade?
« on: February 22, 2012, 01:44:01 PM »
Would these make any difference over stock rear shocks for a 76k? Or are they cheap crap?

Consensus is that they're no better, if not worse, than OEM. Basically you've gotta spend around $300 to upgrade your rear shocks.
If it's worth doing, it's worth doing twice.

Progressive Suspension for stock quality or a little better. If you can afford Hagons then do so, great shocks.

For the money these are good basic entry level shocks Got mine with chrome heavy springs Have had them about 2 years and they are holding up well. Any thing less and you will be disappointed IMO
About $300 I doubt the ones in the op hold up a year.

How much you weigh or if you ride two up a lot or carry a lot of gear on long trips. If you weigh over 200# or do the other things get the heavy springs.

I weigh 170lbs but if I go two up then a good average might be 250-300lbs but the springs only go up to 190lbs. Something isn't right here, am I missing something? Is the lbs rating for each individual spring?

If you are going to do a fair bit of 2 up riding then spend the money and get some good shocks, cheap shocks just heat up and fade and are no better than the stockers, I use have used  Koni {now ikon} for years and never had a problem, Hagons are good as well..

I replaced my worn out stock shocks with some cheap crap from JC Whitney and they are a fantastic improvement.  Problem: sorted.

lb ratings on a spring is how much weight it takes to compress the spring 1 inch.  190lb spring weight sounds really high.  The springs are also holding part of the motorcycle up also, so they have that weight already compressing them.  When you order Hagons, Dave Quinn will ask you how much you weigh and if you ride with a passenger/gear and will make a recomendation.  He also includes a free spring change to a different weight if you don't like them.  http://www.davequinnmotorcycles.com/

So many choices for the Hagons, kewl!
I don't have a motorcycle, sold it ('85 Yamaha Venture Royale).  Haven't had a CB750 for over 40 years.

Dynoman has the best prices on Progressive shocks with springs. I have a set on a K7 and they work fine even when worked into bumpy corners hard. The other stuff is way overpriced for the small added change in bike handling. You  have to consider the value and theory of diminishing returns. I just ordered another set  for a second bike. I don't need adjustable damping on an antique during spirited riding. There is the bling factor and bragging rights for $50-$1000 shocks on a 1500 dollar bike. People buy overpriced 5hit for various reasons and there is nothing wrong with that so long as it makes you happy.

+10 Most people will never use these high dollar shocks to there full potential The op does not sound like he needs them.
 To many want to be racers. Not all of you just 98% of you. The money would be better spent on some lap time on your bike and a good instructor.

Same for Ikons, and more choices of shocks.... ;)

The main reason for most people  that buy quality shocks is because good suspension improves the performance of the bike overall {its not about being happy} it's that they are better shocks, last longer are completely rebuildable, built from higher quality materials, and reduce braking distances considerably over cheaper quality shocks and are less susceptible to fade ,  its like the old saying "if you have a 50 dollar head then buy a 50 dollar helmet", i would say i probably buy better tires than a lot of guys here as well, not to be happy or for show, to have piece of mind knowing that if i come off {which i never have from my own doing} i have either made a mistake or been run down by an idiot in a car {that has happened}, nothing to do with my choice of suspension or tires.... Good suspension and tires saves lives...   rotortiller, adjustable damping and rebound help keep your suspension in contact with the road under brakes and on bumpy surfaces, while riding or braking, far better than non adjustable shocks. If you were to run into someone that pulled out in front of you whilst riding with me, wouldn't you be curious as to why i was able to stop 20 yards before you and avoid an incident.? While you are replacing your cheap shocks i will be replacing some oil and a couple of $5 dollar seals, i have bought 20 years old Koni's that still work as intended, i would love to see that on on cheap non rebuildable shocks, just doesn't happen....

+10 for bowling ball. Spoken like a wise and practial man. My bad on the typo, that was to mean 500-1000 shocks.

I thought $5 dollar shocks were a bit cheap.

I think some of you guys have it wrong with the boy racer comments, quality shocks doesn't mean they will work better at speed it means they do the job they are designed for better than cheap shocks, thats why suspension components have come so far in the last 40 years, most standard shocks on modern bikes these days are far better than the cheap shocks you guys talk about for the same reasons. The main benefits are better road holding and compliance over the average road, shorter braking distances more contact for the tire to the road under brakes and more comfort, its the same with cartridge forks over the older style damper rod forks, you don't have to be going fast at all to notice the benefits, a wise man knows their benefits and the reasons for their use, saving money isn't always practical. If you know the differences it makes for a more informed decision, thats what i call wise and practical....
