The Stinky 2-4 is a great platform for upgrades too- the stock cranks/fork/shock are all heavy. Great for gravity assisted stuff but for the typical trail riding we have around here it’s a lot of weight to pedal around and climb with. I was able to drop quite a few pounds off my son’s Stinky 2-4.
-Air fork/shock to replace the original coil fork/shock
-hydraulic brakes to replace the cable disc brakes
-shorter cranks with external bearing BB (the original Howitzer BB weighed a ton)
-wheels are ones I built up with lighter rims, trail tires set up tubeless to replace the heavy ass DH tires
