1972 Penton "Jackpiner" 175cc. Made by KTM in Austria. Frame number 7- 209 57908, built Sept. '72. Engine number 2- 52 01549, RH center engine case clock on 6-72. First year for KTM engine, first year for the 175, and first year for chrome moly frame. This frame has the air induction under the seat, it is not the later high-breather / frame-breather chrome moly frame which may be indicated by the use of the 1973 model, fuel tank and fenders.
After sitting for apx. 4 years, last week I looked it over, gassed it up, and got it running on the third kick. Overall this Penton is in very good condition for it's age. You could possibly hit the trails tomorrow with only a little prep work. Everything is there and functions, it appears nothing needs immediate attention, or replacement - it sounds healthy, and feels strudy.
The chrome steel wheels are in outstanding condition compared to what you'd normally find on a '72. There's one touch of rust apx. 1/4" in dia. on the front rim, no flat spots or dents. - The pipe is great, only one small dent on top, in the middle, near the seat trim piece on the right. It looks like the original paint on the pipe. - The kickstand, and kickstand mounting area on the swingarm look flawless, where 95% of them you see have been damaged there. - When sitting on the side stand, the bike stands up straight as new.
The seat is very nice, rear seat brackets still the original black paint, no rusty screws, solid and clean base, very nice old-school replacement cover. - The tank has some epoxy around the RH petcock, not too bad, tank looks and works good, clean inside, does not leak. - Fork seals should be replaced . - Nice Ceriani 32mm forks, straight, never rusted. - The aluminum lower fork legs look remarkably nice for their age.
No broken cylinder or head fins, side cases are very nice, but need repainting. - Original MotoPlat ignition w/lighting wires, has a very strong spark. - It was converted to a Mikuni carb (don't know the size), nice job on that. - Tires are amost new Dunlops. - Has nice (not bent) tubular case guards. Front part of skid plate is missing. - modern aluminum handlebars. - Like new airfilter. - Magura levers are in vgc. - Old Falk Dirt Champion fenders are in vgc. Rear only has a couple small scuffs. - Needs a grip on the throttle side. - Needs the nylon chain block on the guide. - The tank strap is nice, not stretched out around the filler hole. - The Mulholland rear shocks have very little time on them ,and function well.
A little paint, and a few repro parts could easily make this a great looking Penton.
