Dear Oy,

Many thanks for your letter of the 21st. I am sending you a German paper we had translated, of which a few paragraphs are interesting, relating to the increased /u obtainable in a forward direction when driving over that obtainable when braking. If you have already seen it or when you have read the parts that matter, please send it back.

I have spent a most enjoyable time reading your paper in the blue book, and am now looking forward to a little heckling.

To get the maximum possible speed on a turn would it not pay to lean the outer wheels inward and get help from the camber thrust? Could not therefore a motor-bike take a given curve faster than a car.?

I will keep further questions till we meet, except whether 4 ply tyres have the same cornering power comfort ratio as 6 ply tyres of the same size.

Yours sincerely,
