OS Engines O.S. Max 21Xz-B

Designed with the club, 1/8th scale, off-road racer in mind, the Max 21XZ-B draws on many of the features developed for the top-of-the-line Speed 21XZ-B and has then been simplified technically to make a more cost-effective engine for everyday sport use.

The Max 21XZ-B is still pumps out an amazing 2.55PS at 33000RPM so she\'s no slouch, but weight is a little higher without the exotic materials of her glamourous sibling.

Throttle response is typically \'OS\' from the type 21J2 carburettor and very much class leading. The heavily finned crankcase and cylinder head give optimum cooling in the warmest weather conditions and even look \'cool\' as well!!

Get an advantage over your competiton, get the Max 21XZ-B
