Ti-4 Titanium Mesh: the least expensive of Yonex Japan’s six titanium racquets of 2001
Six titanium racquets, and the cheapest
In April 2001 Yonex Japan’s titanium mesh line ran to six racquets: the Ti 10 in its long and regular lengths, the Ti 8, the Ti 7, the Ti 6 and a newcomer, the Ti 4 Titanium Mesh. At ¥16,000 before tax the Ti 4 was the least expensive of them, ¥3,000 under the Ti 6 and ¥8,000 under the Ti 10, and Yonex pitched it at intermediate players. It was a Japan-market model: Yonex’s export catalogs of 1999 and 2000 have no Ti-4, and no export listing of it is documented. It also lasted. The Ti 8 and the regular Ti 10 ended production in 2001 and the long Ti 10 in 2002, while the Ti 4 stayed on sale in three successive colors until Yonex Japan ended its production in 2005.
Mesh for control, a shaft that bends
Yonex Japan described the Ti 4 in two lines: the face-stabilizing effect of the titanium mesh made it easy to control, and the large flex of the shaft sent the shuttle far with little effort, a titanium racquet for intermediate players. The 2001 page gave the materials simply as all carbon plus titanium mesh; Yonex Japan’s later pages spelled them out as an all-carbon frame with titanium mesh and an all-carbon shaft with a built-in T-joint. The Ti 6 above it had a high-modulus carbon frame. Yonex sized the Ti 4 in 3U only, with grips 4 and 5, and published no stiffness rating, balance or length for it; “large flex” is Yonex Japan’s description of the feel, not a rating.
No player on record
No player is documented with the Ti 4. Yonex Japan’s pages for it name no user, and Yonex sold it as a racquet for intermediate players. Its siblings are different: Yonex Japan’s advisory-staff pages of 2003–04 list Hafiz Hashim with the Ti 6 and several staff players with the Ti 10.
Turquoise, bright yellow, ice blue
Yonex kept one item number, TI-4, through three designs. The first, on the April 2001 page, was turquoise (color 161), and Yonex Japan filed that design with its 2002 old models. Bright yellow (151) followed and was filed with the 2004 models; ice blue (308), the last design, was filed with the 2005 models, the year the Ti 4 ended. When the later colors went on sale is not documented. The later pages replaced the 2001 stringing advice of 15–18 lb mains and 17–20 lb crosses with a single 15–20 lb range and added a made in Japan line; a later version of the ice blue page lists grip 6 as well. Yonex Japan recommended BG65Ti strings for hard hitters and BG68Ti for control players throughout. All three are the same racquet; Yonex made no limited or player edition.
Five seasons in Yonex Japan’s lineup
The Ti 4 is first documented on Yonex Japan’s racquet list of April 2001, where its page is tagged new; it is not among the titanium models on Yonex Japan’s 2000 new-technology page or in the 2000 export catalog. The ¥16,000 price appears on the 2001 and 2002 pages; the 2004 and 2005 pages give none. By June 2004 the titanium line had narrowed to the Ti 7, Ti 6, Ti 4, Ti 2 and Ti 1, and Yonex Japan lists the Ti 4 among the models whose production ended in 2005, with the Ti 7, Ti 6, Ti 2, the Isometric Ti Swing Power and the Carbonex 20 Muscle. An unused Ti 4 today is old stock about twenty years old or more. No verified sales are recorded yet.
Sibling mix-ups
No counterfeit of the Ti 4 is documented. The likelier mistake is with its titanium mesh siblings, which share the look and the naming: the Ti 6, Ti 7, Ti 2 and Ti 1 were all sold beside it in Japan (the Ti 2 and Ti 1 have their own pages), and the Ti-5 and Ti-3 of Yonex’s 2000 export catalog are different racquets, as is the Japan-only Ti-3L; it has its own page. The Ti 10 and Ti 7 carry the raised Muscle Power Frame, which Yonex Japan’s 2001 list does not mark on the Ti 4. A frame sold only as a Yonex “Ti” is not necessarily a Ti 4, so the printed model name decides.
Outlasting the flagships
The Ti 4 outlived the titanium flagships it was launched beside and ended in the same year as the Ti 6. Yonex named no successor. Titanium mesh stayed in Yonex Japan’s range on the Ti 7 until 2007 and the Ti 3 (item code TI-3L) until 2009; it has its own page. Within that family the Ti 4 was the entry point of 2001, sold for five years in three colors that now date a frame to its period.
Look for the model name Ti 4 Titanium Mesh; Yonex Japan’s item number is TI-4. Match the finish to a design: turquoise (color 161) from 2001, then bright yellow (151) and ice blue (308), the last. Yonex documents an all-carbon frame with titanium mesh and an all-carbon shaft with a built-in T-joint, in 3U only (grips 4 and 5; a later page adds grip 6), and its pages for the bright yellow and ice blue designs state made in Japan. Yonex published no stiffness rating, balance or length for it. A raised Muscle Power Frame between the grommets points to a Ti 7 or Ti 10, and a 2U frame is not a Ti 4. On a frame this old, check the head, joint and grommets for cracks.
The Ti 4 is a modest Japan-market titanium racquet whose interest lies in the family it belongs to and in its three colors, which date a frame to its period. No player or edition story attaches to it. Buy on the printed name and the color, confirm the 3U class, and expect a frame that has been strung and played for many years; ask for close photos of the head and joint.
