I'm just curious what are the differences in weight of each of these motors? Also, what is the power potential for each on a basic bolt on setup? I own a 700R and it's great, but I am a triker at heart. I have several three wheelers in my corral and nothing beats the thrill of a trike with a decent amount of hp. I currently have a Tri-Z with a Cr500 motor in it, but it's rigid and lowered suspension make it nothing but a drag trike. Looking for a good power plant for a duner trike that can still hold it's own on the drag strip. I'm thinking a 700R motor would be great. Lots of torque, electric start, and still has reverse. With just the big 3 and a cam, these motors are producing ~50hp to the wheels depending on the dyno, and that would be almost perfect for a trike with a +4-6" swinger in the dunes. But, I assume it also weighs more than the 450. Given the same mods, would the lighter weight be enough to compensate for the 236 cc's less? It also wouldn't have reverse, which isn't necessary, but is nice now that I've had it. I'm thinking the 450 would fit better in the trike frame, but I've already seen a few guys on the trike sites with 450 powered trikes. This would eb the first 700 I've seen.
What are your thoughts?
