Frame rake question

[Jay Brown]

Does anyone know what the steering head rake is on a 75 250 Penton frame? And did they change the rake from a 73 Jackpiner on the 75 250s?

[JP Morgen]

Not sure about the rake being different, but on the 175 I had, may have been a '72, the distance from the crank to the front wheel was lengthened starting with the '73 250's, cornering was not as good as 175's. When I raced vintage with Penton 250 and 400's, I always put the engine in old 175 frames!

[Jay Brown]

So the 250 motor will bolt into the 175 frame? the motor mounts are the same?

[JP Morgen]

175, 250, 400, all the same

That helps me a bunch, Thank you, JP
