High Performance

Yes, you are right, the “UPGRADE FORKS AND REAR SHOCKS ABSORBER KIT” I bought it’s GREAT: I have really increased the stability in both medium and wide curves as well as in braking. VERY SATISFIED.
Fast delivery in Europe and correct seller, absolutely recommended. A little bit attention in packaging.
Special thanks to Matthew.
