Please note: This bike is a part of the Northern California Superbike Collection. The anonymous owner is well-known and a long-term friend of both Iconic and Bike-urious. All proceeds will go towards a foundation he and his wife run to further research for sustainable agricultural and agroforestry systems worldwide.

For the 1999 model year, Buell evolved the S1 Lightning into the X1 Lightning. Changes included visual updates along with a stiffer tubular steel trellis frame, a switch to DDFI fuel injection, and an improved seat. What’s more, the X1 Lightning was known for its distinctive cast-aluminum subframe — one of the largest applications ever seen on a bike. As Cycle World put in their review, “Everywhere you look, you note improvements over previous Buells, from the new instruments to the new footpegs and forged foot controls to, yes, the helmet hooks under the easily detached seat. The Xl feels like a complete industrial product; no parts remain that hint at kitbike, or of the compromises necessarily made when Buells were built in a Mukwanago garage at the rate of one per week.”

In that same debut year, Buell decided to offer a limited edition called the Buell X1 Lightning Carbon Fiber Extreme. The lengthy name came from the distinctive carbon fiber bodywork which was woven with a blue-tinted Dupont Kevlar fiber by deBotech.

The special carbon fiber was utilized all over the place: on the front fairing, chin spoiler, tank cover, and windscreen – look closely and you’ll see the Buell Pegasus icon weaved into the last piece.

Just 250 examples were built, all of which featured Nuclear Blue wheels and frame, and a numbered gas cap. MSRP was $11,299.

This example is VIN: 4MZSS56J2X3220213.

The odometer shows 5,279 miles.

It is #98 of 250.
