Rear Shock Options
So I'm currently looking at new shock fir the Hawk. Currently looking at these 2 DNM shocks i seen guy on here use the 1200lb 295mm at 80 bucks said was way better over stock requires some washers between bushings and he had it filled with nitrogen. And there is another DNM MK AR 1000lb same dimensions little more pricey at $118 that might be little better. Also seen the keoghs that is recommended on the hawk website.

I have seen alot of posts with riders installing this shock.
Seems that everyone of the day it is a night and day difference. I am actually thinking of installing this exact same shock but I would much rather order from Amazon. There are tons of them listed there as well and the same price. |

I have the Keoghs adjustable shock found here. https://www.aliexpress.com/item/3281...3-76cdf671bc30
It is listed as 320mm on the options list, but is in fact 325mm. The extra 5mm in length will result in about a 1/2" higher ride height than stock with the suspension at full droop, and the total stroke of the shock gives the rear about 7 inches of total travel, which is just a bit more than the stock shock. The spring rate for these shocks is 1200lb/in, which is perfect if you are a bigger guy (200+lbs). I have yet to bottom out my rear shock and I get full travel from it. If you are a lighter guy (sub 200) then the 1000lb spring rate will likely be more ideal for you. Just be aware that any small change in length will translate to roughly a 2.54 times change in height - Courtesy of OneLeggedRiders figures and results from a 30mm(1.18inch) shorter shock - 290mm - lowering his bike 3 inches. This figure also exactly matches my change in ride height with a 5mm longer shock, which if you do 5 x 2.54 you get 12.7, which is exactly 1/2 inch. Interestingly enough, this also means you can easily calculate a ride height change from the difference in length in mm to ride height in inches thanks to the conversion for a mm to an inch being 25.4, and the ratio of length to right height being 2.54. Literally slide the decimal of the length difference to the left 1 point and change mm to inch. Example: a 30mm shorter shock = 3.0 inch decrease in height. Or a 5mm longer shock = 0.5inch increase in height If you are curious about how that works we can run through the math. Take 30mm times 2.54 to calculate the change in height, which is 76.2mm. Divide 76.2 by 25.4 to convert to inches and you get 3. Obviously this isn't an exact thing since the arc of travel of the swing arm will alter the ratio some, but for the range of motion we are dealing with, it is more than sufficient.

It’s been my experience the past year that this shock is decent on fire roads but bounces down the highway like a pogo stick. 60 mph or 30 mph it makes no difference and repeatedly rebounds. You can get the back tire off the ground like skipping a rock if you let it keep rebounding. Deaccelerating sharply or standing is the only way I can get mine to quit bouncing. The 1200 295mm is what I have.

Your experience is quite different from mine. My shock performs wonderfully on and offroad with my 6'2" 260lb frame. It's not bouncy at all on the highway and I have the rebound damping set 3 clicks from firm. Due to it's reduced travel (the 290mm) I can get it to bottom out offroad but you have to work at it. There's a little bridge down from my house that I jump in 4th gear, and 90% off the time the rear suspension soaks up the landing without bottoming. |

My shock was also shorter than what i ordered , received a 300mm and i ordered a 310mm. I got some of my money back when i filled a claim , shock cost $104 and i got back $57. It seems the quality control is not good and luck plays a big part, kind of like buying a china bike most have great bikes but some have problems. I still need a rear shock but i will probably get mine from amazon or ebay or wherever i can send it back if i get another dud. I don't know the ratio of good to bad but so far its 50/50 as in oneleggedrider and megadan both got good ones and chiptoothy and myself got bad ones. Almost forgot , but mine was a Khoegs from ALI and came from china. |

Now the TBR7 on the other hand.. The stock shock may have adjustable preload but all that thing does is bounce.

There is a plug on one end of the shock that could be the nitrogen refill port but i don't have any stuff to even do such a think anyway. The big problem with my shock is the rebound clicker can just be spun around and around in either direction with maybe 3 clicks total in one full rotation every now and then. I plan on stripping the shock down and cut it open if necessary to see what's in it and how the rebound clicker is supposed to work , I will post pics of course so people can see on this site. |

Just so you know eye to eye stock is 12 inches (on my bike ) or 304mm. If Jay decides to upgrade he can raise (310mm-325mm ) or lower the bike ( 275mm-295mm). Also as megadan and you pointed out the 1200lb spring is good for more aggressive riders or 200lb plus weights and Jay could get away with the lighter 1000lb spring. |
