400ex vs CR80R (WHY?!)

I cannot for the life of me figure out why. BUT, my best freind that I grew up with (I am 30) since we were like 8 told me that his step sons "new" bike would beat my 400... ITS A CR80R. Its a 92 model I believe. it is piped, but we have no clue what else.

we went riding and had some openings in the trails and I was surprised that I could not out run him.

anyway it was time to settle it. we lined up and ran. I was sure I was going to walk him after the launch. I have fresh tires on my 400 and they hook up well on the dirt road we were on. I launch hard and hit second and pull on him. hit second hard and wheelie through the gear, and hit third hard and I hear that he is still there. I look back and I am not pulling away anymore. Shocked I stay in it and we let off (I was in 5th) and ahead by a bike length or two. Second race. same thing.

Third race he hooked up better. I still pulled a bit, but in third he over took me and into 4th quit pulling on me and I started to real him in when we shut down in 5th.

fourth race. SAME THING! he could consistently beat me to third gear (with me getting a better launch everytime.) we switch. I have about 20 lbs on him... pretty much same outcome.

I swore the bike was not an 80, but on the block it says 82cm and on the frame its taged 80cc...

HOW?! WHY!? I know the 400's are not the fastest thing in the world and my bike is pretty much stock. BUT, holy cow. I cannot believe how fast an "80" is... HOWEVER, his step daughter has a 80cc honda four stroke thats a 2000+ model and that thing is crazy slow...
 
Back when I was in high school, my friends dad bought his little brother a 95 cr80r. He was telling me he couldn't get it to wind out. I told him I would.....I was shocked. They lived on a farm, and had about a 400 yard straight away in a field. I hopped on it, went ripping across the field, ran out of room, and slowed down and went back to the garage.

I don't know where you have been..:confused: but just about any motorcycle will outrun a 4 wheeler. Its the hp to weight ratio. You have 4 wheels to move and 380 lbs with about 27 hp. He has 2 wheels and about 200 lbs with about 20 -25 hp. The 80 cc 4 stroke has about 12 hp so you might be able to beat him ! :p

any 2 stroke dirt bike can out run just about any quad

my brothers 85 could pass a pred 500, but not by much

they are lighter, more HP, and with more hp they can gear and use tire size to get top speed
 
them old Honda 80's were the best ones they did in my opinion my kids recently had the same Cr 1993 though iirc made into a sidecar outfit and it scared to death many fully grown adults as said no bottom then bang 20+hp at the back wheel lol steering dampered and proper geometry it torque steered the front tyres bold when it actually hooked up

yeah, lol... when I first rode it I thought there was something wrong with it. no power at all. Then I finally just hammered into it, and OMG. thats an amazing little bike once you figure out the power band and when to expect it. lol. I did smoke his blaster and his dads sportsman with my 400. but from 1-5 gears that 80r was anyone's race. I won 2 or 3 and he won 2. it became a drivers race at that point. I was shocked.
I swore it was a 125 with 80 plastics! that thing is honestly faster than the yamaha 125 my buddy has. (not proven yet, but that may be the next race). I hope to have a go pro next time.
 
with decent traction the 80's will stay with anything until they top out then the bigger bikes just keep pulling its no fun drag racing though get some laps in lol

I know. he just was telling me that it was faster. I said I dont think so. and after we had been out riding on the ATV trails and backroads all day he said "well, lets settle this!!!"... I am always down for a race.

I guess its time to "mod" the 400 now... ;) hes going to be mad. his blaster wont keep up with it as it is (my blaster deffinitaly wont keep up with it either).
 
if you went for a long distance you would probably beat him because of top speed, the cr80 is "quicker" but not necessarily "faster"

and yes my kx85 i had would run with my friends predator if i could get it to hook really good, but only until we got moving at a pretty good speed he would pull away pretty fast and then disappear as i topped out
