競技版（5300系列） 

AST Suspension 競技版5300避震器。

為了獲得最佳表現，AST Suspension設計了3-way 可調競技用避震系統。 5300在伸側的部份擁有12段調整可以回彈速度。

在縮側的部份 分高速與低速閥門高速壓縮部份有12段調節，低速壓縮更多達14段調節。

兩個壓縮調整都是在外掛式氮氣瓶上來進行調整。所有調整閥門完全獨立運作。

結合多年的 技術 測試 經驗，在彈簧的選擇和相應的阻尼特性之間創造了完美的平衡，這使得它成為每個客戶適用的產品。

5300系列避震器是每個賽車隊對操控的最佳解決方案。避震器易於安裝，高可靠性，並且選擇使用高強度材料，讓比賽期間達到最低的維護。

所有的這一切讓5300系列避震器ㄧ次又一次成為許多賽事冠軍得主所使用的避震系統。 AST 5300 Suspension在全球許多賽事以其各個層面表現優良並穩定而聞。

優點包括：

• 5300是ㄧ款頂級規格的避震系統，容易調整 不管是在賽道或街道使用

Competition 3-Way (5300 Series)

For the best performance on the track, AST Suspension designed the Competition 3-way adjustable series.
The 5300 Series shock absorbers are rebound adjustable in 12 positions on the strut.
The highspeed compression is adjustable in 12 positions and the lowspeed compression is adjustable in 14
positions. Both compression adjustments are made using an external canister. All adjusters work completely
independent.

Many years of technical knowledge, testing and experience has been refined, fettled and brought together
to create a perfect balance between the choice of springs and the corresponding damping characteristics.
This makes it a versatile product for every customer. The 5300 series shock absorbers are the best solution
for every race team. Once installed te scock absorbers are easy to setup, highly reliable and require low
maintenance during the season because of the high grade of materials used.
All of this together makes the 5300 series shock absorbers a championship winning damper, over and over
again. The AST 5300 Suspension is worldwide renowned for its performance at every level.
