The 1968 BSA Spitfire Mark IV was the last of the three A65 years that the Spitfire was produced from 1966 to 1968. The Spitfire was considered the 'hotrod' of all of the various BSA models. In 1966 it was tested and advertised as having a top speed of 120 MPH right out of the crate; a speed generally considered hard to obtain by production street motorcycles of the time. You can own a Spitfire Mark IV t-shirt with the side cover design on the back. The design is on the back as most premier/upscale events put their design on the back rather than the front of the shirt. The shirts are 6.1 oz. (heavy) 100% preshrunk cotton. Far heavier than other 4.3 oz. shirts being sold. 6.0 to 6.4 oz. are the heaviest t-shirts available. Sizes available are: Medium Large Extra Large 2 Extra Large Postage via first class mail. $4.00 POSTAGE. (My actual cost is $5.00) My '68 Spitfire Mark IV shown is not included with the shirt. Thanks for looking. Ride Hard!
