The 450er is an 08 and there is no specific 450r, just wondering what the difference really is?

 

ER = Electric start. Thats it I believe.

Okay thanks guys

 

the 450r has lower compression and smaller carb

 

old thread revived here but, I believe that depends on year. I was thinking all is same on equivalent year r and er.

 

the 04-05 have like 10:5:1 and the 06 and up are like 12:1:1 or something like that and in 07 some came with fuel injection and the 04-05 also have a smaller carb but some people say the 04-05 carb will help an 06 and up but i wont put one on mine....and yea sorry about the old news i just thought it was interesting

 

In this link they have the same Keihin 40 mm flat-slide with throttle position sensor (TPS)
Carb.

06 and up has 42 or 43mm

 

Nope even Hondas Site says the same as link above. Keihin 40mm flat slide carburetor with throttle position sensor (TPS) Honda Media Newsroom - TRX450R - 2008 Honda TRX450R/TRX450ER Specifications

They can,t be both wrong.
