Athena Big Bore 70ccm

Revolutionary cylinder kit from Athena, unlike many other kits on the market that use stud bolts, this Athena Big Bore with flange mounts directly to the block.

Athena has come up with a stroke of genius in the design of their Big Bore cylinder kit with their flange mounting. For example, there is no need for studs all the way up the cylinder because the cylinder is now mounted with bolts at the bottom and this has left a lot more space and free hands to design and optimize larger exhaust ports and flushing channels which ultimately results in more performance.

Based on years of experience, thorough testing, analysis and not least advanced technological solutions, there is potential for unprecedented performance for an air-cooled cylinder kit . This kit is with ø10mm cross pin.

Note: Due to the special mounting conditions, it is important to carefully read the supplied manual before installation.
