A good question for you guys!!

[4everhonda]

Me and my friend are arguing over this and I figured you guys could settle it! I will list my 406ex's options and tell me if it will beat a stock 450r

406 11:1 JE piston kit
High velocity intake porting
Cleaned up exhaust porting
Stage 1 hotcam
39mm fcr carb
Aluminum no lid air box
K&N with precharger
Full HMF exhaust system
Vortex Prgramable Ignition system
Stock front and rear gear
Stock Size Tires
Barnett dirt digger racing clutch(yeah doesn't help speed but I thought I'd throw it in)

it will be close but im sorry to inform you that a stock 450r would most likely take you unless you are a better rider.
