Roketa DB40 (aka GY6)

Dragon · 03-04-2011, 02:57 PM

Some of you may recall I had a Hibird 250, which is a GY2. And it had crappy frame and suspension, but I did really like the light weight. I found this GY6 for pure dirt only. So priorities are the frame and suspension. Please take a look at the suspension linkage below. Did China fix the lack of travel problem that plagued the GY2 and GY5? I wonder how this suspension stack up against the Qlink?

Personally, I would look into the Qlink.

Your linkage looks like gy2 and gy5 . there are a few threads on here about different mods and shocks .

That looks to be inspired by the Honda Pro-link. If you install a longer link (shaped like a dog bone), I believe you'll lower the seat height.

The rear link on the GY6 looks like the ones on GY2/5. But I wonder if the lengths of the linkages on the GY6 have been changed. The GY2/5 have linkages that would bind; thus the amount of travel is ridiculously low, like 3 inches.

Looks like this discussion is really moot. Because, as it turns out, that website doesn't actually sell the GY6s.

Not sure about all the GY2's but on my Hibird 250, the shock limits travel. My shock recently siezed and I am in the process of changing to an R6 shock. All the travel is now there so I dont think it was an issue with linkage.

I can also say that with the R6 rear shock , i have at least 3 " of drop when i sit on my bike and it has lots of remaining compression . very plush and controlled ride with the adjustments on the shock .
