Thought I would post a few pictures of my Champion Triumph. I built it 30 years ago, raced it until 2017, and now believe it or not I am selling it. I just posted it in the for sale area. I am posting a couple of other pictures here only so that y'all can take a look at it, and so I can look at them and enjoy them without thinking about selling it. It is a little like selling a family member, this ain't easy, but life goes on and it is time. Maybe it's only fitting that the House of Charmin at Willow is in the background of the first picture, LOL.

Like all bikes that get raced a while, it is sort of like George Washington's ax that he chopped down the cherry tree with--4 new handles, two new heads, but it is the original ax. Similarly, this one started out in a Redline frame before the Champion, and I sawed the engine in half at Barber circa 2006, and again at Miller in 2012 or so when the transmission exploded, and I changed the forks and tank and seat and transmission and clutch/primary and basically everything else several times, so other than those few things, it is just the same bike as in 1989. Man, I am going to miss it!

Cheers!

Hey Linker, how about sharing some specs on the bike? Looks like it has 4spark plugs, big carbs, Big bore headers, (which look really nice). Have you dyno graphs? Or other info on it, race results etc.

Thanks for the questions. I put a full list of the detailed specs in the for sale area, but basically the engine is full of durable race parts, pretty much all the moving parts except the rocker arms are race parts. Makes mid-60’s hp on a Dynotech, and above 50 lbs/ft of torque from 5000 to 7000, went high 120’s at Daytona but it’s really a lap time torquey motor–lap times win races pretty much everywhere but Daytona and Road America–even Willow. The engine and chassis work as a package.

Over 25 years of racing it I’ve won a few races (LOL very few) and finished well in a few years of points Ditto–very few), but really I do it for fun and racing from Alaska is a bit of a challenge to do a full season. But the bike’s very competitive with the best Yamahas, and hey, besides that I’m a Triumph guy.

On the pipes, I pretty much did what the real experts said. I duplicated exactly what the late Jack Wilson at Big D said (1-3/4 diameter 29 inch with 13-1/2 inch megs to 3-1/2 and a 1 inch long reverse cone to 2-1/2), and the late Neal Keen told me he’d tested about every combination of 1 3/4 or 1 1/2 or 1 3/8 pipes and chose the big ones. Those pipes spun up well but didn’t have much below 5000. On these up pipes I added 2-1/2 inches of length on the head pipes and a 4 inch long 2-1/2 diameter muffler at the back of the Meg–both changes added a lot of area under the torque curve for lap times usefulness.

Hi guys, the longer winter goes on, the more I am missing racing this thing. I'd be pleased to sell it, let me know if you are interested. [email protected]

Shame it's not being used. Bet there's a racer from the east coast that would fly in and exercise it for you at Laguna next month!

Sure is a nice bike. I saw it for sale but that part of my life is probably over...

Now that is funny, I'm sure there is!
