Motorcycle News - Grom Reaper: What Zero designers get up to after hours
Motorcycles are another matter, though. It’s an engineering nightmare, and you obviously lose the stealth aspect, because the motor is on display. But that didn’t dissuade Cole Mishler, who has just built the ultimate pocket rocket: A Honda Grom with a lithium ion power pack and more torque than a Yamaha MT-09.
The first question: why?
“The stock Grom has a tiny frame and a low-performance engine,” Cole tells us. “So I saw the potential to really showcase the power and quality of the Zero drivetrain.”
The Grom Reaper has more than double the power of a stock Grom, with 27 hp rather than a humble ten. Torque goes up by a staggering +800%, from 8 to a heady 66 ft lbs. (That’s almost as much as a Harley-Davidson Sportster 1200.)
There’s a moderate increase in top speed from 56 to 66 mph (106 kph), governed by an enormous 55-tooth rear sprocket that’s almost as big as the 12-inch wheel.
Space was quickly cleared out in the R&D department at Zero HQ in Scotts Valley, California.
“It was actually pretty easy to sync up the Zero drivetrain. We started by stripping out the ICE parts and the stock wiring harness.”
Once the motor, controller, and battery were mechanically mounted to the bike, Cole installed a new wiring harness and spliced the Grom’s lighting into it.
The last mod was to ditch the 31mm stock forks and fit more sophisticated Öhlins units. At the back, there’s a matching remote reservoir shock.
It’s an electrifying little package, and with the ridiculous abundance of torque, probably the most fun you can have with your clothes on.
We’re hoping the folks in Zero’s C-suite are smiling too. How about putting something like this into production, guys?
