    Awesome!!!!

    Question -- you mentioned adjustable rebound. Is this on the rear shock? If so, how'd you get that with the Shock Solution kit? I'm starting to seriously consider that instead of the Cogent route because of cost difference... $289 vs $600.

    If you look at the item just above the shock solution kit you'll see the shock shaft assembly. It's basically the same thing as the Cogent. Although I'm not completely familiar with the Cogent, it was explained to me the Race Tech shock shaft assembly is better (I'm not saying it is, it was explained to me to be better).

    Absolutely! Young or new people always want performance mods, and limit their definition of performance to speed and power because power numbers are easy to compare and brag about. But, real speed involves turns too, and a confidence inspiring suspension will add more performance to most bikes than engine mods ever will. Before adding that loud 1 additional horsepower $400 wide open can, absolutely work on the suspension!! Good, well-adjusted suspension will go a LONG way towards making you a better and happier rider. I haven't experienced a stock DR, but mine with up-rated springs front and rear, intiminators, and rebuilt shock is more stable and confidence inspiring than my sportbike.

    The Shock solution kit for $289 is nothing like the Cogent rebuild. or the full shock shaft assembly from PC.
    It is a great budget rebuild improvement but is not in the same league.
    The Cogent rebuild kit is $295 if you can do it yourself (spring NOT included) and it gives you full adjustment.
    Or for $399 you can have them rebuild yours for you (again, spring is extra)
    Their optional Mil spec coating is not required and you don't get that with any other rebuild so don't add that $ to the Cogent cost.

    So, the bottom line is that if you want the best, you want full adjustment, comp & rebound, and if you need a different spring, the Cogent costs under $500 and they do the work, or you can spend $498 for the Shock Shaft assembly and you do the work.
    Kinda seems like an easy decision to me... :huh

    I have only recently purchased my bike so I was wondering what maintenance stand would suit me best for general tinkering.

    I picked this up from Supercheap for $149 and I think it works well

    It made the chain adjustment and lube really straightforward. It was easy to spin the bike and move it around as needed.

    I also took off my frame guards and cleaned up under there. It was filthy as and well worth the effort. I had also taken off and cleaned up my bash plate when I did the oil change - again well worth it. I have put a zip tie on my side stand switch and that saves some hassle - the side stand pivot has been cleaned and lubed, too.

    I worked out what chain and sprockets the PO had installed. It turned out to be a 525 with 14F and 41R. I am thinking of going for a 42R and a 15F and 16F to cover the options. What do you think?

    Anyone else got a different fave workshop stand?

    Actually, I've got the exact same one and find it great. I saw it on special for $99 a few months back but nonetheless is still worth the $150. I can actually move the bike around whilst its jacked up, up have never had an issue of it toppling off. Great for turning the bike around! :D

    Have fun. :freaky

    I agree 100%. The adjustable rebound is worth the cost alone. Depending on your weight, you can still use the stock rear spring. Rick told me to stay with the stocker. He's not gonna try to sell you something you don't need.

    I have been told the Race Tech unit has a larger diameter shaft than stock and therefore more bearing surface area. Other than that, I'm not sure how the Cogent differs from Race Tech.

    The $498 includes a new spring. If you get the shaft assembly only from Racetech it's $399.99 minus %15 = $339.99

    Sweet looking ride and I love the low front fender. Wait a minute, an English wheel in the background..........Did someone say talent?

    With about 7500 miles on the beast today I changed out the rear and front brake fluid.

    Here is about the first inch-worth's of fluid coming out of the front... :lol3
    Hope I put newer fluid in it in time to prevent the front from seizing up too soon.

    I've taken flak for the fender & a lot of stuff I built for my DR, but I don't give a shit it's the way I like it

    .70 front?

    That would be a stiff ride...

    Could be. I went slightly less than Race Tech recommends and the guy that set up my suspension mentioned the stiffness of the springs, but he followed up by saying that he thought I was right to put in significantly stiffer springs. He said many of the people who bring him suspension work refuse to believe they should be running spring rates as high as they should, so they change the compression/rebound and run springs too soft for the weight they are running (either their body weight or how the pack the bike), or their style of riding. So, bottom line is I figured the springs are pretty cheap and I might as well use Race Tech's recommendations as a starting point. I'm not sure it's right or will be over time, but with the small amount of riding I've been able to do since yesterday, the bike feels very well balanced over rougher terrain. It definitely feels like the front and rear are working together as opposed to feeling front and rear separately (I used to feel the front and then the rear when going over terrain; whereas, it now feels like one fluid movement). I think the rebound is much much better.

    Racetech changed their spring calculator a while back and it shows a lot stiffer fork springs than it used to. I just tried it a minute ago and it recommends .72 for the front and 7.9 for the rear for my 195 pounds. I have had .50 in the front and 8.1 on the back for a few years now.
