Yonex EXBOLT 63 – ultra-thin 200 m reel for quick repulsion
The Yonex EXBOLT 63 is a modern performance badminton string for players looking for an exceptionally fast response, strong repulsion and a highly lively string bed. Its 0.63 mm gauge makes it one of the thinnest strings in the Yonex range.
The specially braided Forged Fiber outer structure is designed to provide greater resistance than conventional ultra-thin string constructions. This enables the EXBOLT 63 to combine explosive performance with practical durability for such a thin gauge.
The 200-metre reel is particularly suitable for clubs, competitive players, frequent players and professional stringing services. Depending on racket head size, stringing pattern, knotting technique and string usage, it provides approximately 20 to 22 complete badminton racket restringings.
Playing feel and characteristics
The EXBOLT 63 provides a medium-to-hard, direct and exceptionally responsive impact feel. The shuttle leaves the string bed immediately, allowing players to generate considerable speed with short and fast swing actions.
Its greatest strength is quick repulsion. Drives, attacking clears, counters and smashes receive dynamic acceleration. The string is particularly effective in fast doubles, where early contact and short explosive movements are important.
The thin gauge also creates precise feedback and a high, crisp hitting sound. Net shots, blocks and controlled placement can be finely managed when the shuttle is contacted cleanly.
Despite its resistant Forged Fiber outer structure, a 0.63 mm string remains more sensitive to off-centre contact, damaged grommets and heavy abrasion than 0.68 or 0.70 mm alternatives. The EXBOLT 63 is therefore clearly performance-oriented rather than a dedicated durability string.

Important: At 0.63 mm, the EXBOLT 63 is very thin. Damaged or sharp-edged grommets should be replaced before restringing. Always observe the maximum permitted stringing tension of the badminton racket.
Who should choose the Yonex EXBOLT 63?
The EXBOLT 63 is particularly suitable for advanced club and competitive players with sound technique. It works well for fast doubles specialists, attacking singles players and dynamic all-round players who take the shuttle early.
Players with medium to very fast swing speeds benefit from its immediate acceleration. The string supports quick drives, aggressive counters and powerful attacking strokes while retaining precise feedback during controlled play.
The 200-metre reel is economical for clubs, coaches, frequent players and stringing services that regularly prepare several rackets with a high-quality ultra-thin performance string.
Beginners with frequent off-centre contact or players with especially high string wear will generally be better served by a thicker option. The EXBOLT 65, for example, offers more durability, while the EXBOLT 63 places greater emphasis on speed, repulsion and immediate feedback.
Our recommendation
We recommend the Yonex EXBOLT 63 to players and stringers looking for maximum speed, strong repulsion and a distinctive hitting sound from an ultra-thin string. It is particularly suitable for technically skilled and pace-oriented players.
