My buddy said my bike is older than a 78 and previous owner said it is a 78. VIN number 855 09896
sorry forgot to put the question in. Can anyone determine what year my KTM is from the VIN I listed above. Thanks Wardie
Wardie, from what I can find it's a 78. The first digit is the year. I'm no expert on this so someone else might chime in to confirm.

The 855- identifies that bike as a 78 MC-5 model. If the serial number had been in the 9950 or higher range, it could be a early 79 model called the MX-6. So far, the MX-6's that I have found started around serial number 855-10315 and higher and were only produced a couple of months or less. Mike

Picked this 175 up the other year and had the notion it was a MC-5, however after reading the above I'm wondering if this would be a MX-6 ? VIN# 855-10664

I thought the only difference between the MC5 and MC6 was that the MC 5 had the cog in the shift drum so that you only used 2 - 6th gear, whereas the MC6 used all the gears. Of course the suspension is different too; MC 5 had the longer set-up.

MX6 is a very early 79 model using a 855- left over 78 MC5 frame and with extra holes in the fork damper rods improving the harsh 78 forks and fork boots and a couple other improvements. All ktms had 6 gears, but a few had 1st gear locked out with a bolt that could be easily changed to allow all 6 gears to be used. A very limited number of MX-6's were produced, maybe 30-45 days. Search MX-6. Mike

Mike,I think I have a set of 78 35mm forks. Any chance of getting the info on fixing the damper rods. Cheers Bill
The MX-6 250 has 38 mm forks, so I am not sure that it would be necessary or beneficial to 35 mm forks. I still have a MX-6 250 that I have yet to restore, but if I remember correctly there were 2 sets of holes drilled in the damper rods, with the 2nd set about 1-1-1/2" farther up and at 90 degrees around from where the lower set were drilled and about 1/8", but I would have to dismantle a set to get an accurate measurement on the 38 mm forks. I had read an article in a magazine about doing this same modification on the stock 78 38 mm forks because of their harshness, but can't recall which magazine, but I probably still have the magazine with the 78 MC5 test article here somewhere.

Thanks for the info Mike. Perhaps you can post it if you find it. I have two bikes with 38mm forks from around that era so it woild be helpful. Bill
I found the article. It is a 78 MC5 250 test in the November Cycle magazine. On page 34 it tells about the hydraulic lock that occurs upon contacting square edged bumps and high speed jump landings and forearm fatigue. It tells to drill another compression hole 1/2" above the existing hole and make it the same size, and position it 90 degrees from the existing hole. The compression hole is the lowest one on the damper rod, and it will make the forks as good as any on the market. It also states that Can Am's already have this modification done at the factory in Canada. Mike
