Isometric Tour 300: Yonex USA’s Medium Stiff partner to the Tour 800
The softer Tour
The Isometric Tour 300 is known from a single Yonex source family: Yonex USA’s Isometric Series pages of 1999; the main page printed it second of four racquets, after the Isometric Tour 800 and ahead of the 250 Long and the 90 Light. Where the Tour 800 was rated Stiff, with high-modulus graphite in both frame and shaft, the Tour 300 was rated Medium Stiff, with a graphite frame and a high-modulus graphite shaft. Yonex printed no item code or price for it, and none of its Asian catalogs or Japanese lists on record names it. Its name also invites a link to the “Isometric 300” Peter Gade remembered from his teens, a link no Yonex source makes.
Graphite frame, H.M. shaft, 2U
Yonex USA’s spec block for the Tour 300 lists flex Medium Stiff, a graphite frame, an H.M. graphite shaft, weight 2U (90–94 g) and grip G4, and recommends 16–18 lb on the mains and 18–20 lb on the crosses. The page’s series copy says the Isometric line paired the isometric head, which makes main and cross strings equal in length, with the built-in T-joint “for more stability,” and that it “created the most successful series on tour for the 1997 season,” naming no model. Yonex published no balance, length or country of manufacture for the Tour 300. A US club’s price list for 1997 already offered an “ISO.TOUR-300,” so the racquet was on sale in the United States before Yonex’s earliest surviving listing of it.
Gade’s Isometric 300, unidentified
No player is documented using the Isometric Tour 300. In Yonex’s Legendary Players feature, Peter Gade recalled “my ISOMETRIC 300, which I used as a teen pro” and called it “a revolutionarily flexible model.” The same feature says Yonex signed him at about 14 or 15, and he turned 20 in December 1996. Its gallery of his racquets begins with the Isometric Slim 10, dated 1997, and pictures no Isometric 300. Yonex gives his racquet no item code or year, and its own rating of the Tour 300 is Medium Stiff, so no Yonex source ties the two. Wikipedia’s uncited equipment list for Gade gives an “Isometric 300” up to 1997. Yonex Japan’s Isometric 300 Long came in 2001, too late to be his teen racquet; it has its own page.
Four Isometrics on one page
On Yonex USA’s page the Tour 300 matches the Isometric 250 Long line for line (Medium Stiff, graphite frame, H.M. graphite shaft, 2U, G4), so in print only the name separates them. The Tour 800 shares the 2U class and G4 grip but is Stiff, with H.M. graphite throughout. The 90 Light is the softest and lightest of the four: Medium Flex, all graphite, 3U (85–89 g). The Tour 800 and 250 Long have their own pages. Yonex USA’s small product photo shows the Tour 300 with a dark frame and orange accents on the hoop; Yonex names no colorway or edition. Yonex’s 1999 Asian spec chart, which lists the Tour 800 and 250 Long, has no Tour 300 column.
Listed in 1999
The Tour 300 appears on Yonex USA’s Isometric pages in May 1999, the earliest record of them, and the pages still showed it, unchanged, in April 2001. They did not change while the export lineup did: the 2000 Asian catalog had dropped the Tour 800 and 250 Long that shared the page, so the pages’ later years date no sale, and 1999 is the last year a Yonex lineup documents the Tour 300. No production end is documented, and no Yonex price for it survives. Yonex Japan’s product and old-model lists never name it. No verified sales are recorded yet.
Checking the name
No counterfeit of the Isometric Tour 300 is documented. The likelier mistakes are of identity: the 250 Long carries the same printed specification and the Tour 800 the same Tour name, so the printed model name decides. A frame printed 300 LONG is Yonex Japan’s 2001 model, a different racquet, and a seller’s “Isometric 300” may mean either, or the racquet Gade remembered. A frame about 25 years old deserves a close look at the throat, the hoop and the grommets.
A late-1990s export Isometric
The Tour 300 belongs to the late-1990s export Isometrics; by 2000 Yonex’s Asian catalog led its Isometric pages with the Ti Swing Power. It came after the Isometric 500 of 1992, which brought the square head to badminton, and alongside the Super Isometric 10 of 1996, Yonex Japan’s hollow “razor frame”; both have their own pages. For collectors it is the softer, plain-graphite-framed partner of the Tour 800 in Yonex USA’s line, with a name that keeps it close to the open question of Gade’s teenage racquet.
Read the shaft for the model name: Yonex USA titled the racquet ISOMETRIC TOUR-300, and the head should have the squared isometric shape, with the built-in T-joint Yonex describes for the series. Yonex USA lists a Medium Stiff flex, a graphite frame with an H.M. graphite shaft, 2U (90–94 g) and grip G4; no Yonex source lists another weight class, a balance or a country of manufacture, so treat a seller’s figures as unverified. Its product photo shows a dark frame with orange accents on the hoop. A frame printed TOUR 800 or 250 LONG is a different racquet, and a 300 LONG is Yonex Japan’s 2001 model.
The Isometric Tour 300 is a piece for collectors of Yonex’s pre-titanium export Isometrics, documented only by Yonex USA’s 1999 pages. Buy on the printed name, the squared head and the 2U class. Treat a seller’s claim that it was Peter Gade’s racquet, or of a Japanese version or another weight, as unproven until a Yonex source supports it.
