The reason you don't want inverted forks on a high speed trail/desert bike is normal cartridge fork flex more, letting the rider ride longer. Inverted is great for MX or short races. A fork brace will bring our stock fork to about 70% of what inverted fork are for a compromise. That will help stop the side to side flex but still allow the front to back flex.
600cc engine can put out a lot more then 55bhp at the crank (that is what a CRF450 puts out, as well as our stock uncorked XR650R) that being 44hp at the rear wheel.
The husaburg 650 puts out 52hp to the ground stock. So, 48hp to the ground out of a 600cc bike to the ground would be easy. Add a few extras (Uncork it) and push that up to 55hp???
The reason for the CR500 shock is that it has high and low compression adjustments and is only 5/8" longer then the XR650R shock. The CRF450 shock is to long.
The aluminum frame thing looks and sounds cool
but, it is way more ridged and heavy. The XR600R frame is lighter then the XR650R frame. This is where the burg really shines.
Lighter weight swing arm with more room for bigger tires.. more clearance to the fender for big paddle tires
Rollers on the rocker arms
and better cam (more lift and more duration) let the engine rev just a tad more and less friction for more horsepower.
Don't need the engine to rev above 10,000rpm so, titanium valves are not needed (or wanted).
Most needed to get everyone attention is less weight
257 pounds would be what the XR400 is and what the CRF450X is so, why would you need them
Every race guy wants the Magic "E" button
The FCR41 pumper is on the CRF450.
Lower gear?? As in the tranny?? with more horsepower
and more torque why?? I pull second gear starts with 15/49 now...Oh, wait I have a 680
If you mean sprockets that is a rider thing. This is a Baja bike
115mph is what my bike does/has been to.
The rest is up to the rider. Bars (they should be moved forward and higher) and the rest can be added by the rider to make the bike fit. But, I agree it should be made for a guy that weighs 190~210 pounds and is 5' 11". I am not that big but, it's an average
not, 150 pound guy from Japan.
The XR is more than a bike - it's a culture. The latest/greatest craze can't claim that, so we need to keep our bike alive if we don't want our culture to go down the toilet with it.
Okay, I've compiled a list of upgrades/changes that we've talked about. What else needs to be added? We should collaborate with Borynak and everyone else to get a comprehensive list together, and go through it before submitting it, so that it actually makes sense to Honda. No point sending them a wishlist that's impossible to do - a list of things that can be made into a complete package should be compiled instead. So, first of all, changing the engine and the frame are likely not going to be possible, for cost reasons. So we need to determine if we can live without those changes. Of course, if Honda's already into the development cycle, we're screwed. This is what we have so far:
Pumper carb (possible?)
CRF rear suspension
- heavier spring for a heavier rider
- once again, heavier for heavier rider
New rad guard/new rad?
New front light/number plate - if they beef this up to a Baja style, I think it'd really sell - an oversized light with an aluminum cage, or maybe dual oversized lights and no cage.
Engine - more hp? I don't think this is possible at this stage
Lighter frame - also likely a very $$ change. I say we work with what we've got.
Bigger tank - sorry Acerbis, I like the size, but I don't like the look!!
Electric start - I don't know if this would go over with the Baja crowd. Maybe for the L version.
New name - XRF?
Renthal crossbar - Renthal won't make this cheap for Honda. how about a Renthal-style bar??
Better thermostat - should be possible
Okay, let's get more added, then go through one-by-one.
