Rare and pristine set of Bos high-mount open exhausts in beautiful aluminium. This set-up resembles the stock Superbike and Superlight exhausts and therefore doesn't interfere the stock look, unlike carbon fibre options.

They fit:

• 851 Superbike

• 888 Superbike

• 900 SS Supersport

• 900 SL Superlight

Bos is a small, reknowned Dutch workshop and in back in the day, they used to make exhausts for these bikes. They sound and to most, they sound even better than Termignoni. I am no exception. I spent a few hours getting this set back in shape. Jobs done:

• removed quite some dirt and chain grease on the sleeves

• treated the aluminium 5 times with WD40 to remove any older dirt and to conserve the metal

• cleaned the stainless steel link pipes with Commandant Cleaner no. 4 and then sanded them

• removed most of the charcoal in the outlets

No dB-killers, so officially "for race use only", however the sound it produces is unparalleled.

• Connection: 40mm (fits stock manifolds)

• Weight of box: 7.4 kg
