Hasi Tuned developed R21 Aluminium Liner

During the recent 1:8 Onroad World Championship in Japan, Silvio Hächler stripped down one of his engines to give us a close up look at the new aluminium liner that has been developed and manufactured by Hasi Tuned.  The major advantage of the new 9 Port AAC liner is the much reduced break-in timed needed compared to the latest conventional ABC liners used by O.S.  The benefits of the new Hasi Tuned liner which after initial machining goes through two more separate processes before being hand finished and matched with a suitable piston, is that it can be fitted in any OS R21 track engine starting with the old R2101 and ending with the latest R2105.  The big advantage however is that it is extremely easy to break in with 1.5 litres having it race ready.
