Available in limited quantities for the first time in decades!!!

The Bonneville Shop is pleased to offer new 10-stud cylinder heads for Triumph 750 twins by LF Harris. Made with new castings based on the last of the Triumph 750 twins, this dual carb parallel port Bonneville head is correct for 1978.5 onward Triumph Bonneville twins with Amal MKII carbs, but can also be fitted to 1973-78 Triumph 750 twins (airbox and other modifications will be necessary for 1973-78 twins, contact us prior to purchase if you are unsure what this entails). Suitable to replace excessively worn Triumph 750 heads, & perfect for anyone wanting to convert their single carb TR7 to a Bonneville 750 for added top end speed (again, airbox mods will also be necessary to convert). This head comes with valve guides, just lap in the valves of your choice and assemble from there. This head also features screw in style exhaust ports to allow fitment of exhaust stubs and use of push over exhaust pipes, a vast improvement over the leak prone push in exhausts fitted to most 750 Triumph twins.  UK made & very limited, why take chances on a used cylinder head when you can have new for a few dollars more?!

Also available with valves & springs, see recommended links


LF Harris motorcycle spares are produced to the highest quality standards possible utilizing original Triumph tooling, dies, factory blueprints & materials combined with modern manufacturing equipment, tolerances & techniques.
