Recently I moved my entire shop, and residence to relocate back to the San Francisco Bay area with one goal in mind, violate San Francisco!!! I grew up here, but moved to Grover Beach to get my manufacturing engineering degree at Cal Poly San Luis. I ended up getting stuck there for 10 years! Not a bad place to get stuck, but daydreaming about San Francisco on the dirt bike consumed my thoughts. it was a 4 hour drive and with my crazy schedule, didn’t happen very often. Now, I am all up in it, crazy spots to hit everywhere, shooting videos and photo shoots all the time, and love it!!! One of my long time friends hooked me up with a San Francisco photographer Christophe Tomatis, http://tomatisphoto.com/, and the results have been mind blowing! Christophe is down for the cause, gettin dirty on the ground, hittin the illegal spots, hangin out of cars, getting sniper shots from the bushes with the telephoto lenses and coming up with creative lighting, angles, and ideas that have brought my dreams, to reality! I have so many awsome photos now that it is difficult for me to process. This recent shoot was on a bike I just completed after a few months of developement.
I got a bone stock 2007 yz250f , with 30 minutes on it from my aluminum delivery driver.
I never thoght I would like a 250 after owning a wr250x ( wich was a huge dissapointment) but the yz250f motocross bike is not even comparable! I love this bike. it is super light, (205 dry) very snappy, and handles better than any bike I have hit a corner on.
I designed a prototype Dual Caliper Rear Handbrake system (www.50stunt.com), a custom rear subframe with foot hoop and stunt pegs. I also had to jump on illustrator and design my custom graphix!
I also added Supermoto Axle Sliders Front and Rear, along with some case savers to protect the engine, and some billet handlebar ends to save my levers when I slam the bike on the earth.
The last thing I needed was some street rubber to really rip the city up. I have never like the 17 inch small wheels on a dirt bike, i personally think they look wak. my goals was to keep it lookin like the dirtbike that it is, so I wrapped some street tires on the stock wheels and tried it out. The front was good to go, but the rear did not circle good, the bike wanted to stand up and circle super wide and not lean in, even after experimenting with time pressure from 10-40 psi. It just didn’t work. My solution was to hit up Warp 9 Racing http://www.warp9racing.com/ and get a custom set of Supermoto Wheels goin.
I ended up with a 21 front with a 320mm rotor and caliper adapter , and a 17 inch x 4.25 rear with rear rotor and 51T rear spocket. Then I put a baloon tire on the rear, lol, with a tall profile as close to the stock 19 with knobbie as possible in overall diameter. I ride this bike on the mx track all the time also, so the Warp 9 wheels coming complete with rotors and spockets makes it so I can change to my dirt setup in minutes! I love the results, the bike handles awsome, rips, and spins on a dime! Thats all I added, I call it my minimalist build, engine is bone stock ,gearing is all stock, just 2 up in rear for the mx track. quick swap to go to dirt trim. The key components to convert the dirt bike to a supermoto streetstyle machine are
- Rear handbrake kit
- Front and rear axle sliders
- handlebar ends
- warp 9 wheels ( you can get away with 17 only in rear, stock front)
- custom subframe with foot hoop and stunt pegs
- street tires
All are avaialable at www.50stunt.com. The Final Result is my favorite bike to date!!
So I texted Christophe Tomatis, The San Francisco Photographer, and we did work! hitting the streets, peirs, fishermans warf, some jumps, traffic, everything!! here are a few photos, more to come, along with some sweet videos!
some screen shots from the street session!
keep checkin it cuz its about to get real urban!
