“It has been awhile since I have shared any of my project bikes with MXA. Here is my most recent build, a 1995 KX125 built after one of my childhood hero’s–Robbie Reynard. As you can see the original platform was in pretty good shape which made things easy. I started by sending the frame out to Curry Custom Coatings for a fresh coat of Kawasaki Green powder.

“The engine came in a box, the cases and cylinder were sent to Eric Gorr Racing to get the cylinder repaired, as well as a Team Green spec port job and case matching. The engine was assembled with all new bearings, seals and gaskets from Hot Rods, Winderosa, and a Vertex piston.

“The engine cases, swing arm, frame guards, brake calipers and master cylinders were sent to KE3 Restoration to be Vapor blasted, to bring back that show room finish. The clutch cover and housing were also sent to Curry Custom Coatings to be Cerakoted for the factory magnesium look. I also sent all of the OEM hardware out to be re-zinc plated.

“When everything was back in my possession, I began assembling the chassis where I used All Balls Racing bearing and seals, the forks and shock were rebuilt by Dan Elings at Race Pace Performance where he also used All Balls components as well as Race Tech Gold Valves. The stock hubs were Powder Coated to resemble the factory look and were laced using Pro Wheel Racing spokes and hoops.

“I was able to source an original Braking 270 oversized front brake rotor and coupled with a Tusk Racing Honda-style stainless brake hose to insure that it stops on a dime.

“This build would not have been possible without the help from the following.”

WHAT ARE THOSE NUMBER ON MY SHOCK SPRING?

springnumbers

Dear MXA,
One day while adjusting the shock spring on my KTM I noticed a row of numbers. I had never seen them before. I asked my buddy what they were and he said a serial number, but another guy said they were the spring rate. He didn’t know why there were two numbers but guessed that one number was kg/mm and the other inch-pounds. What are they really?

You were as close as you could get while still being totally wrong. See the 54-260 on the spring above? The first two-digit number is the spring rate. The spring rate is 54 Newton/meters. The second number is the free length of the spring—which in the photo would be 260mm long. KTM does not use kg/mm, but if they did this spring would be a 5.5 kg/mm spring. The idea that the second number represents inch-pounds doesn’t work for two reasons: (1) No one in Austria has ever heard of an inch, let alone an inch-pound, but if they did a 54 N/mm spring would be 477 inch-pounds.

THE NEW MXA IS OUT: INSIDE IS THE 2021 MXA 250 SHOOTOUT, HIDDEN SECRETS OF THE FACTORY & ROCKSTAR EDITIONS, PLUS TWO EURO 250 SMOKER TESTS & ALL THE GOOD STUFF YOU EXPECT

There are also some accessories available to use with Polisport’s ProOctane: The filling hose + cap, that will make the filling process easy, with a fluid stream of fuel. This system has an auto-stop device to avoid the spillage of fuel; Also available separately, the filling hose (without cap); and very soon; the quick fFill system for those who need an even faster pour rate.
