Hyperpro Streetbox - Opinions?

So, I am in dire need of some suspension work, especially in the front. I was originally planning on buying Sonic Springs 1.0-1.1 kg (w/ everyday gear, I'm pushing about 230lbs and ride 2-up often). Then I was gonna wait for a really good deal on a rear shock. However, I came across the Hyperpro Streetbox listed at a MSRP of $699.00 USD. This comes with a new rear shock, progressive springs, fork oil (might use something different here still), and a nifty box with stickers! Also, there is a lifetime warranty on the springs and a 5-year warranty on the shock.

Opinions?

That's one thing I'm concerned about. Is Hyperpro legit when it comes to quality? I know for all of the other rear shocks alone that I was looking at, it would be a minimum of about $600-$700. Let alone including the fork springs and some oil.

Greetings Militiascene,

I installed the sonic 1.1s, now it helped some but I now know I need to do the gold valving as the front tire pulses on heavy cornering plus the ride is still hard.
Should of bought the valving instead of a new seat but didn't.
Can't afford to do anything with the rear shock yet but needs to be done. Dang theses things must be made out of gold $$$$

Here's another option I was looking at:
Daugherty Motorsports - Motorcycle Suspension Performance and Modification
CBR929 Conversion
(98-01 only)
$420

This is a DMr exclusive and one of our most popular items! This conversion takes a standard CBR929RR shock absorber and converts it so that it is a direct replacement for the stock VFR800 shock. The shock would also have a new spring installed that is tuned to the rider's weight and type of riding. The revalving service replaces the piston with a DMr high flow version and custom tailored shim stacks for the best performance possible. Price includes the donor CBR shock so nothing would need to be provided by the customer.

They have this same shock for the Blackbird.

Actually, I'm with Stex about this one. I talked to Daugherty and almost went that route. I'm thinking that for the same money, you could have Daugherty build you a replacement fitted just for you, and get a great set of whatever springs you like.

Nitron Sport shock is only $600 for an exceptional shock from what I have researched. I'm looking at one of these as well as doing the front with valves and springs. For another $180 over Jamie I think the Nitron is alot better than a modified stock shock. JMO

Plus 1 on the nitron, loving mine and you can buy the base model and add preload adjusters down the road if you desire and can't afford it now. I bought the more expensive unit and haven't even adjusted it, would have gone with the basic one if I had to do it over. The nitron also comes with height adjustment, nice bonus.

Have to say, I'm extremely pleased with my Nitron rear shock as well, though I went for the full boat including the step up to the double adjustable track shock, and the external preload adjuster.

That being said, everyone has different needs and budgets. The solution from Daugherty can provide very high performance at a cost allowing for a new rear shock plus front springs. Any of the suggestions here are good.

BTW, I think one advantage of the Daugherty option over the Nitron sport shock would be that the Daugherty is I think a remote reservoir double clicker. The Nitron sport is a single adjuster. The Track Nitron (what I have) is a double clicker, and the Race is a Triple. That being said, don't know if that is really necessary for the OP.

Can I add my 35 cents worth ? I have been doing the research for a full upgrade for a little while now. The more you do. The more confused you get. One suspension tech that I talked to said that he would recondition my old standard shock and that it would perform just as well as an expensive aftermarket one. When you think about it. If the internals are replaced by good quality ones and it is set up for the rider, then why shouldn't it . He also said that the internals of a well known expensive shock are all put in to a uniform standard and that they often take a brand new shock. Strip it down and rebuild it to suit the customer. Makes sense also. Another suspension shop told me that I had to replace the standard with an aftermarket to achieve any significant improvement. Scratch Head ! The first shop I spoke of has very good reviews from customers and is hundreds cheaper than the next. They will also set the front and rear to suit me. They will do the whole job in a day while I wait for it, so I think that is the way I am going to go. Plus if I am not happy with the ride, they will do any mods that are needed for free.

Greetings Hammy,

With all that said whats the $ amount for all that tuning? Sounds good,,,,but it's been a known fact on this site that the showa shock is so so and the forks are a wreak. So whats this dude going to do, rebuild, replace,what?

I ride my sons cbr600 and I say why can't the Blackbird ride be like this?
So and was just wondering what your service tech was going to do while U sit the sipping tea, coffee, or an adult beverage of your choice.

I truly know service techs cause I been one my whole life and I understand there bull corn tricks.:rolleyes: question everything!!!

Stex, out

So, from what I can tell from everyone is that Hyperpro has pretty decent products. With the condition of my suspension at 44k miles on the bike, this should prove to be revolutionary. And for the price, I would say I get quite a bit. As long as everything works out financially, I should be ordering in the near future and will post reviews after I get around to installing it and getting a feel for it.

That does not seem like a great deal to me. If that's $1450 Aussie dollars, that's not that much less than what I have in my Nitron Track double clicker with remote hydraulic reservoir, remote canister, and full Ohlins super bike rebuild for the front forks. I had to pull the forks and ship them, and swap the rear shock, but....

I would also say that it's very possible to build a very nice performing shock using some OEM components. I would not say you'll build a great one using an OEM xx unit, but stranger things have happened. Having played with these and other components, one thing I am absolutely certain about.

There is no possibility IMHO that an OEM XX shock can be made to equal a really good Ohlins, Penske or Nitron. Again, IMHO there are simply no "equal" "good parts" to be used to make them perform the same. There are simply tons and tons of differences. Shaft size, length, stiction, valving and metering, gas charge - all kinds of stuff. If this was not the case, don't you think that top racers would be using these? At least some?

That doesn't mean you "need" or would necessarily even notice the difference. Who knows. I know my suspension at this point is far more capable than I am as a rider.

I have no idea what the shop you're talking about is doing. All I know is that if something is that much cheaper to get the same result, there's probably a reason. Other places would not allow themselves to get constantly undercut if they could provide the same results for less.

Good points wmhjr. I don't think for one minute that the shop tech, or I think that a rebuilt oem unit will come close the the others you mention ( in certain circumstances ). I think what the tech is claiming is that I will notice a big difference in normal riding conditions. Will smooth out the little bumps. Remove the wallowing and just make it a better riding experience. If I was to want the bike for track days or was a rider that goes 10 10ths all the time then I might need the top notch gear to handle it. I am 99.99% sure that I will go with this tech and hope that it is money well spent.
