2007 model will be aluminum frame
My local dealer says that Yamaha has all but officially confirmed to them that their 2006 thumpers (both YZF and WR) will have aluminum frames. I guess we really won't know for sure until June 15, 2005?
2007 is the year I'll be replacing my '03 with (unless I just can't live without an '06!)

That frame will be nice, but I'm concerned that engine longevity will not be what it was when the oil reservoir was in the steel frame. It really helps to cool the oil as we all know. I wonder if Yamaha will be able to use the alum frame in the same way? I doubt it. Only time will tell.
Good point, would be good to see an oil cooler somewhere on the new frame to keep the oil capacity up.

I hope for an ally frame, but see no benefit in just doing what they did for the 2-strokes. A new frame material requires a new design. Look at mountain bike frames. Ally ones have totally different aspect ratios to steel frames. I would rather yamaha waited til 2010 and gave us a proper ally frame (just copy the crf one) than rushing out an ally frame based on the frame we have now, with no benefits other than shinyness and corrosion resistance.

i was just reading the new suzuki 450 will keep its oil in the trannie,good for the trannie bad for cooling! where is the honda oil ? in the trannie also? and if thats true is it gonna be a seperate case like a 2 smoke? sounds like a need for a oil cooler to me. and whats wrong with incorporating it into the aluminum frame? i thought aluninum had a even better heat transfer than steel?
Yeah the crf has half its oil in the tranny/clutch (similar to a two stroke) and the other half for the engine. Only 700cc-ish for the piston and valvetrain. No thanks!

But hey, they spent a lot of time and development on the motors, i guess we can give them a break.

ONLY with this design will have real weight savings...
Notice that a CR250 is not that much lighter than any other 2S with steel frame...same doesnt happen with the alu 2S Yams.

Saddly to all you Jap bike fans, its was decided long ago that only Euro bikes have 6 gears ...and hydro clutch
But our Jap Bikes run and your Euro bikes like to sit on stands and be wrenched on

Actually now i have a Euro 2S...very little wrenching (crossing my fingers ...
Piston & rings once per year...3 years allready now , very hard riding, 6500KM...
Better i change those crankshaft bearings just for sure no matter they seem perfect...

I'm really hopeing the steel frame stays around through the 06 model year for the WR's because by then my wife will have outgrown her klr (really already has) and we'll be buying her a new WR450, If the 06 has a aluminum frame, I'll be searching dealers for a left over 05 (or another 04 would be even better)
