Standard Bore Cylinder Kit

  • Same reliability and performance of the original components
  • Maximum durability and smoothness guaranteed by a special nickel and silicon treatment
  • Gaskets developed with the most advanced technologies to ensure maximum tightness even at high temperatures and pressures

Athena has been constantly investing in cylinder aftermarket replacement parts for more than ten years, to improve their production and performance.

All the cylinders are entirely engineered in Italy by Athena’s R&D Department which has a strong internal know-how and cutting-edge tools to design and test each piece. They are coated with motor-nicksil, a nickel-silicon coating developed by Athena to obtain smoothness and optimal wear resistance.

Athena’s cylinder kits and its components are recognized worldwide for their performance, durability and reliability.

The Standard Bore cylinder kit developed by Athena guarantees the same performance as the original spare parts, extreme reliability and optimal smoothness as a result of the lightweight aluminum cylinder, the barrel with nickel-silicon coating, and a piston designed to reduce further friction.

The kit includes the high-quality aluminum cylinder with standard bore, the complete piston with the piston pin and rings, and all the necessary gaskets.

All the components of the kit have been developed to withstand the highest temperatures, pressures and stresses and have been validated by Athena technicians with severe bench and road tests.

This cylinder kit can be installed without making any changes to the engine crankcase.

Good condition Amazing read.
Format: Paperback
Amazing book shipped in good condition which is surprising since it's a paper back and most my books I got from Amazon have at least a little damage from shipping. Definitely pick up this book if you make games.

My 22 year-old grandson was incredibly happy with this gift!
Format: Paperback
I can't write a meaningful review of the content of this book, because I don't begin to understand it, however, it was one of the things my grandson requested for his 22nd birthday, and he seemed thrilled to get it and he tells me it's a great book, so I can say whole heartedly, this is a terrific birthday gift for anyone who's into computer games.

More Theory than Actionable Advice on Game Design
Format: Paperback
Not a bad book, but not what I expected going in. I read this for a bookclub like event on twitch. I thought there was going to be actionable advice. Like 'do X to make Y feel". The introduction points out that the book is not about the emotional feelings a player receives from games, and this is true. The book DOES provide a language for discussing game design at a more academic level. It is about the theory of how a game feels, and while I didn't agree with everything Steve wrote it was easy enough to follow the thoughts.
