Isometric 90 VFS: the titanium-mesh Isometric Yonex USA listed beside the 62 MF Light
A second titanium-mesh light Isometric
The Isometric 90 VFS appears only on Yonex USA’s site, on its Isometric list from August 2002 to December 2003. There it sat beside the Isometric 62 MF Light with a spec window that matches the 62’s almost value for value: Medium flex, 3U (85–89 g), a G4 grip and titanium mesh. Yonex lists the two as separate models, never says whether they share a frame, and never explains the VFS in the name.
What the spec window says
Yonex USA’s spec window, titled “Isometric 90VFS,” gives Flex Medium, Power 3 and Control 4, 3U (85–89 g) and grip G4. Its feature rows mark Titanium Mesh, Isometric Square Head and Built-in T-joint, and not Muscle Power Frame or UltimumTi. The window prints 16–28 lb for the crosses beside a 7–8 kg conversion, a misprint: Yonex USA’s printable spec sheet gives the same Medium, 3, 4, 3U and G4, and recommends 14–16 lb on the mains and 16–18 lb on the crosses. No frame or shaft material, balance, length, made-in country, item code or price is documented.
No named player
Yonex names no player for the 90 VFS and gives no playing level for it.
Not the 90 Light, close to the 62 MF Light
The 90 VFS is not the Isometric 90 Light that Yonex USA listed in 1999. That page prints a graphite frame and shaft, Medium Flex, 3U and G4, with 16–18 lb on the mains and 18–20 lb on the crosses and no titanium-mesh row, and no Yonex source links the two names. Its nearest match is the 62 MF Light listed beside it, whose spec window gives the same flex, weight, grip, ratings and feature marks. Yonex USA’s printable spec sheet separates them: it rates the 62 MFLT Extra Flexible with control 3, where the 90 VFS keeps Medium and control 4. Both have their own pages.
Listed 2002 to 2003
Yonex USA’s Isometric list names the 90 VFS from August 2002, its earliest version on record, through December 2003, when it shared the page with the Ti Swing Power, the 63 MF Light and the aluminum-framed 23 and 20. By June 2004 the list had dropped it, leaving the 20, 23, 30VF and 75MFLT. 2002 and 2003 are its first and last documented years, not a launch or a production end. No Asian catalog, Yonex Japan or international listing of it is documented. No verified sales are recorded yet.
Checking the name
No counterfeit of the 90 VFS is documented, and no photograph or frame print of it is on record. The full name is the check: a “90 Light” is Yonex USA’s 1999 graphite model, and a “62 MF Light” or “63 MF Light” is a different model from the same list.
A US-only name
The 90 VFS is known from one Yonex USA list, one spec window and one spec sheet. Titanium mesh is its one documented feature beyond the basics.
Yonex USA documents Medium flex, 3U (85–89 g), grip G4 and titanium mesh for the 90 VFS, and recommends 14–16 lb on the mains and 16–18 lb on the crosses; no item code, frame material, color or country of manufacture is documented, and no photograph of it is on record. A “62 MF Light” print points to the model listed beside it, a “90 Light” print to the 1999 graphite model. Inspect the throat, hoop and grommet holes on any frame of this age.
The 90 VFS interests a collector of Yonex USA’s early-2000s Isometrics. With no photograph or frame print on record, seller photographs that show the full “90 VFS” name are the essential check, and any color, material or made-in claim is unconfirmed.
