450r vs built 416 or 440ex

[Matt400ex_17]

Has anybody raced there new 450 vs there old 416 or 440. Will the 450 hold a 416 with cam, carb,hc piston, good pipe? I want the 450 but have a lot of money in the 400 if its not faster why waste 6500.00

if you got a 416 it'll do better with suspension and cam and pipe and everything on it vs. a stock 450r but i'd get the 450r just because

the built 400 will get served! no comparison between the 2..fo' fiddy will dominate

A built 416ex will keep up with and maybe beat a stock 450r....it also depends on what kind of race your in...and a few other factors like gearing/tire size...etc. i havent compared the 2 but a yfz450 and trx450r in a drag race ive heard the YFZ450 beats it by a few MPH...well when i first got my yfz i drag raced them and my 416ex had a little more top speed (it also was geared higher) it all just depends on what kind of race...but if i was you id get the 450r and sell your ex....you wont regret

I haven't raced a honda 450 yet but I had the chance to race a yamaha 450 that had a curtis sparks full exhaust and a K&N filer on it and we were very comparible. I think he had just a little more pull on the very top but that is probably do to his carb verus my stock carb.

[tbainer]

I have never had any overheating issues. I run straight race gas though just to be on the safe side and it gives you a little better throttle response

[Aceman]

I agree with nacsracer27, you should get rid of the Sparks timing key. I doubt your making any more power with all the extra heat.

My 400 with 11:1 HRC jet pipe will beat a stock 450 by about 1.5 bike. I raced three different people the same day all pretty much the same result (with lighter riders it was a little closer).

[montyjcm]

Which 450?

[duneittilludie]

My wife has raced a couple of the 450rs with the hrc kits on her 440 ex and she can hang right with them in a 300 foot sand drag uphill. From what i have seen so far the yfzs are faster with the same mods as compared to the 450r but i have only seen maybe eight or ten of the new 450 rs running on the dunes so far so in time maybe my opinion will change.

[WhiteBros400ex]

My 416ex dosnt get murdered by the 450 cause my friend has one and i ride with him every day, but i mean it beats me and mines barly worked. Pretty much stock motor cept 416 and a white bros pipe stock gearing, and i have works triple rate front shocks more ridder then quad and depends or what you like to do i mean in the long shot the 450r or yfz are better. Im thinking bout getting rid of the 416 for a 450.

[Sandragggen]

Perhaps I've not raced the right one yet but the 450's I've raced in 500'+ have fallen to the 465EX....both YFZ and 450R. I will add, if either have the amount of money thrown into them as I've thrown into the EX I will be toast. From my experience the YFZ has a slight edge on the R. Both are impressive runners out of the box.

yea, I've posted a thread too about my 502 smoking my HRC450R in a drag. In about a week the 450R will smoke the 502 after top end work, full cs exhuast and fcr carb. But the 450r (soon to be 567R) will never have 80ft/lbs of torque like the 502 has.

get the 450r, because of the way they made it you can put all the parts you have on your 400 onto the 450 except for the stuff that has to do with the engine. a 450 with suspension A-arms and an axle with handle better than the 400 and in the end race faster.

[Matt400ex_17]

I have sat on and rode a 450 and i just dont like the way it sits! I dont know if its because im so used to my tags or what but i would much rather just have that motor in my 400 frame screw all the rest. This bike is strictly mx and nothing else and when i raced with the yfz last year it wasnt worth the new bike and my bike then was stock except for full big gun and kn and 14T front it had me top end in the long drag but had nothin on corners.

[ghak99]

2 Local TT racers drag raced their 440ex and 450r. The 440ex is highly modded and went of and left the 450r stock. A pipe, filter, and jets were added to the 450r and the race was then close but, the 440 still pulled away.

I am sure if the 450r had the money spent on it that the 440 had it would mop the 440ex.

But I believe the heavily modded 416 426 440 etc. will easily be able to run with most of the 450r that will be out there, that is with the right riders of coarse.

[lillbro11]

I run neck and neck with a yfz with 3mm stroke kit, clutches, hmf full exhaust, k&n filter and piping kit 125LB rider

also beat multiple 450rs with modded motors running on race fuel. stock 450rs dont even put up a fight. 180LB rider average

also a 400ex with 11:1 compression 416 wiseco, stage 3 hot cam, curtis sparks x6 exhaust, and +6 swingarm 150LB rider I built this bike before the one I currently own.

I'm running a 407 bore with 11:1 wiseco, curtis sparks x6 exhaust, large oil cooler, aftermarket cdi (Idk what brand), k&n filter, and +4 swingarm

this is in sand drags with 10 paddle extreme haulers

to clear up some controversy, properly tuned 440ex will beat 700 raptors and 450s all day.

theres video of it in the 400ex section, heres the link.

i have both and my 416 was faster than my stock trx450. period.

Man, blast from the past. This thread was started way back in 2004 :eek2:

Wow when are you 400ex guys going to realize that if you beat a 450 in a drag race your riding against a amatuer rider ! No 400ex 416,465,will pull a 700 rap,450 piped etc! unless your 400ex is stickly set up for drag racing (thats wheelly bars and huge rear tires) in the dunes would you win against a stock 450, never against a 700 rap .The only 400ex Ive seen keep bar to bar was a 502ex vrs 660 rap . never seen 400ex beat anything!with expert riders!

Now THAT'S not true.

Granted, it gets up there in price, you're never going to get there if you don't get into the head and do some porting, but it's far from impossible, and it doesn't have to be set up strictly for drag racing.

Deffinetly not true.

Dune racers are notorious for building sleepers and not telling you what mods they have, you could be racing a FULL BLOWN stroked raptor and not even know it....all they have to do is leave a stock pipe on it.

The raptors and 450r's that Ive raced, where owned and rode by MX and XC racers and that were far better riders then I am, I still beat them drag racing. And they were NOT stock!!!

A friend of mine owns a 400cc banshee, we've rode together since we were 14...we now are... 27... far from amature riders here and far from expert, I run neck and neck with that shee all day long!!!

[John Noftsinger]

in dunes you can stay close but on grass/dirt you lose big time !on 400ex

[odog]

stock 700r's are good bikes.but there not that fast.i have a 460ex and my bike is on par with a 3mod raptor i ride with one all the time and im alot heavier than the guy i ride with. In short races he beats me by about 2bikes. but we will have a long race soon and im sure i will beat him.when we switch bikes he beats me also. we are about equal riders but the weight difference is too much in a short race.i know i have more topend so if he doesnt get a new ignition before we race, so he doesn't have that topend limiter.the 700r is going to fall to the ex with or with out a weight difference.

It seems you are a little ignorant to what a proper built 416-440 will do.. Just today I owned a 450r. This was my buddy, we have been riding for quite some time, 10+ years.. What does the rider have to do with a straight line race on pavement after the hole shot??? Nothing. The power tells the tail from there on..

[warrior/exrider]

Just depends on the rider, I'm better on my 440 but I win some and lose some against a 450r or a. Yfz 450
