206 pages and more than 210 illustrations and charts, size 8.25 x 10.75 inches. This publication is a reproduction of the March 1984 second publication of the May 1982 Triumph factory workshop manual part number 99-7059. It also includes the May 1983 supplement 99-7089 for the 8-valve T140W-TSS.

This manual is applicable to all 1979 to 1983 750cc UK, General Export and USA models including the T140E Bonneville, T140E/2 Bonneville, T140E/S Electro Bonneville, TR7 Tiger, TR7T Tiger Trail and the 650cc TR65 Thunderbird 650. The supplement extends the coverage to include the 8-valve 1982 to 1983 750cc TSS and TSX models. Obviously, this manual will also be of use to owners of the 1985-1988 T140 Devon Bonneville.

Unfortunately, Triumph was in deep financial trouble by mid-1982 and it is obvious that they were doing everything they could to cut costs. Consequently, the print quality of these later Triumph factory manuals was somewhat compromised by the re-use of images and text from earlier manuals. This re-use is apparent in this manual, as the quality of the images and the density of the text varies within the page and/or from one page to another. While we have done our best to 'normalize' the print density there will still be variations that were just too difficult to correct.

Yet another issue associated with the mounting financial problems was the apparent scramble to introduce new models or variants of existing models in order to encourage buyers. This resulted in a proliferation of model numbers, a list of some (but likely not all) of those variants is included below:

1979 T140E, TR7V, T140D

1980 T140ES

1981 T140PE, TR7T, TR65 (650cc), TS8-1, Royal Bonneville.

1982 TSS, TSX, TR65T.

1983 TSX8, TSX4, Thunderbird 600, Daytona 600.

Consequently, owners of the 1979 to 1983 models are subjected to considerable confusion surrounding the appropriate selection of the multitude of originals and reprints of the various manuals that have recently flooded the marketplace. We encourage you to exercise caution when purchasing a manual for your motorcycle or automobile as many of the reprints found on internet websites are from 'bedroom sellers' at enticingly low prices by individuals that really have no idea what they are selling. Many are nothing more than poor quality comb-bound photocopies that are scanned and printed complete with greasy pages and thumbprints and, as such, are deceptively described as 'pre-owned', 'used' or even 'refurbished'. In addition, they are often advertised for the incorrect series and/or model years. Owners of the 1973 to 1978 750cc machines are directed to workshop manual ISBN 9781588502919.
