The Cycle X Vintage SBK Heavyweight lap record at Road America still stands. What's more, only one bike in the new Next Gen SBK class was able to beat it. Guy on a 140 hp ex AMA Honda RC30. He beat it by less than a second.

"I probably had the best seat in the house. I was out there on the track. Ken's bike went by me like I was stapled to a tree several times in practice. The thing howled past going down the front straight and then swept through turn 1 smooth as glass. Crazy fast." - Big Bob

"Kevin goes by and rails through Canada Corner. The #1 Kawasaki is about 15 bikes lengths behind him and I can feel the WTF? from here. Cycle X wins again." - Big Bob

"Kenny and the team...won again today. ;) They set an all time vintage heavyweight lap record as well." - Mike Rieck

"Have I mentioned how fast that damn bike is? The looks on the modern bike racers faces as we pass them is priceless..." - Kevin Calloway

Cycle X Vintage Racing Cylinder Services

To protect your investment and insure perfect ring seal we are now offering torque plated boring services to the public. Head bolt torque can potentially distort cylinders affecting the accuracy of boring and honing after assembly. Rings won't seal as well and scuffing is likely to occur if the engine overheats. This torque plated boring and honing procedure will be done with the same head and base gaskets being used to make sure of total accuracy.
