Pure speculation on my part, but through very casual observation of the past w/Honda XR-R, XR-L models, it seems that the "outdated" R models morph into the "new" L model. (ie: the current L is incredibly simular to the '99 R, etc)
Following that premise - I wouldn't be surprised to see the eventual "new L" being based very closely to the currently being phased out R model. I think this idea has further credence considering that the '07 R's are apparently only being sold in the US (can't get one overseas, can't get one in Canada, ect). Following Honda
's past model succesion, I suspect if you'd take an R, add the needed emissions equipment, a battery, DOT legal lights, electric start & a reinforced sub-frame w/pass pegs - you're looking at the "new" L model.
I've no idea what might replace the current R. If it's not dropped outright, I'd suspect something with an updated suspension and a more off-road oriented engine tune (ie the HRC
equipment). Considering the R hasn't seen any major changes since it's introduction in '00, (which is "forever" in dirtbike years) it'll either get a major overhaul, or dropped (I suspect dropped. Considering it's a white elephant in the off-road world - aside from the Husaberg & other boutiqe brands, there's no competition/market of big-bore off road bikes & Honda's got the CRF-X to compete for the majority of the open class bikes available, and since they've finally proven it a worthy sucessor of the desert crown with the Baja wins this past year - I theorize they can drop the XR-R with a clear head.)
Again, following Honda's modus operandi of the past, and considering the huge tooling costs of a new model - If you wanna see the new "L", again I say look at the current "R". I propose they'll refit the current R model into the L to compete in the "showroom dirt worthy" dual-sport/adventure catagory with KTM & Husky, (leaving Suzuki
& Kawi to flounder with the 70's tech, not-really-worthy-of-dirt-or-street, dual sports), I foresee Honda dropping the big-bore off-road only "R" model all together, and doing away with the air cooled, short suspended, steel framed relic, they now sell as the L.
