Rocket Bike: Honda “CRF1000RR” MotoBASE Jumper!

IndeeSource builds MotoBASE pioneer Bradley O’Neal a 170-hp “Rocket Bike”… 

Pioneered in the 1960s, BASE jumping is one of the wildest adventure sports ever conceived, in which parachutists leap from fixed objects, hence the acronym BASE: Buildings, Antennas (radio masts), Spans (bridges), and Earth (cliffs such as Yosemite’s infamous El Capitan, a birthplace of the sport).

Recently we got in touch with Colorado’s Bradley O’Neal (@bradley_slums), the pioneer of a sport he calls MotoBASE:

“I am a professional freerider/BASE jumper and the pioneer of a sport I call MotoBASE. I turn moto jumps into BASE jumps and I’ve designed a parachute system for my bikes.”

Since a video is worth a million words, here’s a video of one of Bradley’s jumps — insane!

Bradley had all but maxed out his 450’s potential, hitting Moto-BASE jumps at around 85 hp, so it was time for more power. So he got together with his sponsor K-Chill and builder/engineer Nate Engle of IndeeSource to develop the “Rocket Bike” you see here — a 170+ hp, CBR1000RR-powered hillclimber built to Bradley’s specs:

“This bike was built for MotoBASE and hillclimb racing. Ultimately I want to see how high I can jump this bike before landing under parachute…”

The heart is a modified 2014 CBR1000RR Fireblade engine planted inside a one-off CAD-designed 4130 chromoly billet/tubular TIG-welded space frame — trick! The intake plenum was designed to accommodate secondary injectors and the exhaust consists of stainless steel individual headers, TIG-welded with billet stainless steel exhaust flanges. GUHL Motors modified the stock CBR harness while the good folks at Twisted Development handled the dyno tune.

The bike features stock 2019 Honda CRF450 ergonomics and plastics, with a custom 5″ extended 4130 chromoly/7075 aluminum swingarm.

Up front is a set of KYB forks sourced from a CRF450, while a WP shock handles duties out back — both tuned by JBI Suspension. The bike is rolling on a Dubya/Excel/Talon wheelset with a 530 chain. Weight is 360 pounds, and the Fireblade engine, capable of 13,900 rpm, cranks out north of 170 ponies!

“The bike is super fast obviously and is quite the workout riding it hard. Feels like you’re doing pull-ups when you hit the throttle.”

Below, we talk to Bradley for the details on the “Rocket Bike.”
