Motone Finned Exhaust Clamp-on Heatsinks


Now here’s a product that screams retro. Motone’s Big Fin Exhaust Clamps mimic those ultra-cool finned header pipe heat sinks of yesteryear. Installation is very simple with the split collar design.  Even the Allen wrench is included.

ONLY FITS OEM HEAD PIPES.  Not compatible with aftermarket exhaust pipes.

Motone Big Fin Exhaust Clamps for Triumph Twins.  These clamps are made in cast aluminum in 2 pieces to fit around the top of the header as it is bolted on to the cylinder exhaust stub.

These do not replace the exsisting clamps but rather fit around them.

Designed to look like the Webco style big finned clamps of the 1960s and 70s they also provide additional cooling area to the exhausts and will reduce pipe blueing.

We have made them in 3 versions, one with a smaller inside diameter to fit the 1.5 inch headers of the original carb Bonneville (built from 2001-2008) and another with a larger inside diameter for the EFI bikes (2008-2015).  A third version is available specifically for the 2016-current water-cooled 900cc & 1200cc twins.
