FZ vs. ZRX
Hey Netlore, my ZRX pumps out 123.4 hp on the dyno!:~
I watched an FZ-1 strain to churn out 114 hp on the same dyno. I do have the basic jet kit, K&N, and slip-on but we all know that doesn't make that much difference. By the way, I'm riding down to Paso Robles this weekend. Is that anywhere near where you live?
Looks like you and him/her both need to go check out Ivan's Performance Products
like I did for my FZ. I haven't had a chance to dyno it yet, but I've got a Slip-On and his Kit . . estimated HP is about 131 hp +/- 1-3 HP from what I've heard. I'm looking for a place to dyno mine, but I would certainly put it up against your REX on the Dyno. :~
Maybe once you modify your air-box (again check out Ivan's site) you will give me a run for my money. Off course I could then get a full exhaust and get another 7+ hp :~ But who really needs more than 130 hp on the street ? Even on the track it's nice.
The REX does have more torque, but I would expect that from a bigger engine. What I wouldn't expect is the way power tapers off so quickly. I used this Motorcycle Analyzer
and did some quick research using your ZRX1200R with 123.4 HP and I estimated 84.8 lb-ft of torque and my FZ1 with Ivan's Kit/Slip-On/15-tooth front sprocket (est. HP 131.2 est Torque 73.7 lb-ft). Here's what I found using a rider about my size (180#)
ZRX beats the FZ1 off the line:
ZRX: 0-30 mph in 1.35 sec. FZ: 0-30 mph in 1.38 sec.
ZRX: 0-40 mph in 1.79 sec. FZ: 0-40 mph in 1.82 sec.
ZRX: 0-50 mph in 2.20 sec. FZ: 0-50 mph in 2.22 sec.
ZRX: 0-60 ft in 1.86 sec. @ 41.68 mph
FZ: 0-60 ft in 1.86 sec. @ 40.96 mph
ZRX: 0-100 ft in 2.42 sec. @ 54.98 mph
FZ: 0-100 ft in 2.43 sec. @ 55.15 mph
Then the FZ quickly catches up:
ZRX: 0-60 mph in 2.65 sec. FZ: 0-60 mph in 2.63 sec.
ZRX: 0-70 mph in 3.43 sec. FZ: 0-70 mph in 3.08 sec.
ZRX: 0-80 mph in 4.25 sec. FZ: 0-80 mph in 3.92 sec.
ZRX: 0-330 ft in 4.62 sec. @ 84.67 mph
FZ: 0-330 ft in 4.55 sec. @ 89.58 mph
ZRX: 0-90 mph in 5.09 sec. FZ: 0-90 mph in 4.58 sec.
ZRX: 0-100 mph in 6.43 sec. FZ: 0-100 mph in 5.55 sec.
ZRX: 0-500 ft in 5.89 sec. @ 95.38 mph
FZ: 0-500 ft in 5.75 sec. @ 101.80 mph
ZRX: 0-660 ft in 6.99 sec. @ 104.39 mph
FZ: 0-660 ft in 6.77 sec. @ 112.08 mph
ZRX: 0-1000 ft in 9.07 sec. @ 117.42 mph
FZ: 0-1000 ft in 8.72 sec. @ 125.54 mph
ZRX: 0-1320 ft in 10.88 sec. @ 124.58 mph
FZ: 0-1320 ft in 10.40 sec. @ 134.45 mph
Basically, you'd have me for about 300 ft and then I'd walk away and you'd wonder why you 1164 cc bike got beat by a 998 cc bike
"Does he have a turbo charger?" "Is he using Nirto?"
Okay, I figured I'd better back up my theory of why I see most ZRX's in my rear view mirror. :laugh:
Anyway, Paso Robles is about 3 hours North of me. We're trying to plan some kind of ride for this weekend but we're all playing it by ear.
Once again, I'd like to send my condolences to the ZRX owners for there purchasing decisions :laugh:
(I'm kidding, the ZRX rocks and gives the FZ a good run for it's money. I just prefer the styling of the FZ)
