I think a stock 450r would beat a stock 250r, I had a fairly stock 250r and I rode my friends 450r, yes the 450r will beat it, but it would be very interesting if honda did release a 250r with a powervalve, 88/89 geometry, better shocks, that one would be a tough call, one thing for sure you would have 2 honda's from different era's closely competing for the #1 slot. I like the way the 250r sits alot better than a 450r, the 450r is way too tall, but also so are all the new quads, so honda was following the bandwagon. In my opinion the motor is what really makes the bike, it would be awesome with a-arms, 0 preload shocks, wide axle, smaller tires. I didn't like it too much in stock form,other than a curtis sparks pipe. maybe it was just me, since I was riding my 330r trike, one thing I can't get used to with quads(now) is bump steer, my trike has 0 bump steer, and riding a quad its totally different and all I feel is bump steer. just for the record, I'm building a 88r, don't plan on riding it alot, only so I can go to other places to ride. I know for sure I'll ride my trike alot more and thats why the aftermarket parts aren't coming off it.
