there is no difference in a 100 and 125 Penton. all parts can be changed out.a 100 can use a 125 head ,cylinder and piston .you can change the peace pipe but either works.that is the ONLY diff. in the 2 bikes.when looking for parts bear this in mind.

I'm looking at a 1970 Penton 125 6 day to purchase. The bike is like new in condition. What is it worth?

I do not have a photo but I have looked at it many times and the bike is absolutly just like new in every detail . Thanks for your help. Rex

Cannot advise value. Best bet would be to browse Ebay and the classifieds for similar machines. Ed.

Hi, in North Carolina, US...will get pics this weekend, here is Penton & DKW I am selling too



October 3, 2000
I am road racing a modified Penton, Fichtel and Sachs "Six-Day" 125cc in the 'classic-vintage 250cc' class with the Washington Motorcycle Road Racing Association club here in Seattle Washington, USA. The engine is a stock 125/5A from my original steel tank 1970 model, while the chassis is from a 1972 fiberglass tank model.

These motorcycles were originally imported into the USA as Enduro motorcycles, by John Penton, of Ohio. I've modifiied the suspension but left the engine stock, including the magneto and points ignition, which has been flawless for over 30 years in my engine! I use AVON racing compound tires, 90/90 on the front, 100/90 on the rear, on 18 inch rims. My forks are Ciriani road racing units with 35mm tubes. The front brake is an 8 inch double leading shoe from a Bridgestone motorcycle, which provides very good braking ability. The rear brakes are stock, and reasonably adequate.

I am running a 48 tooth rear sprocket, apparently the smallest I can fit to my hub, and a 15 tooth front. This arrangement provides pretty good acceleration from the starting grid, and about 80 mph top speed in 5th gear. I weigh 160 pounds without my leathers and helmet on, so I guess this is respectable speed. I wish I could get more RPM from the engine, and better top speed, without sacrificing acceleration.

I wonder if the SACHS engine has ever been modified for this kind of racing in the past? What sort of modifications are known to give better horse power and top end torque? (Penton did a pretty good job of porting the engine and he supposedly squeezed 21 hp out of it, but a gp125 Honda does so much better, at 43hp I've been told)

Although actually an American motorcycle, Penton is included here as it is assembled from mostly European components.
