Greetings..I am a NEWBEEE Here but at 49 years old been on bikes all my Life and Now for some crazy reason I am Living in Vietnam for 6 years already. Long way from San Francisco. I just bought a Great condition '07 WR 450f in Cambodia.....Can I just swap my Wheels off my '09 WR250X?? I want to SM my 450 now. I have been thrashing the little 250x up on the Ho Chi Minh Trail near Laos from Da Nang every week for 1.5 years now and the Little thing has had ZERO problems. Very Impressed with my "Commuter" Bike...about 120 k's each way in about 1.5 hrs. I am 6.4" and weigh around the same as a Water Buffalo...about 103 kilos...I am also looking to install a Keyed Ignition switch somehow..I will spend time here looking for different gearing options for this thing due that most of my riding is mountain windy Pavement riding with some hard pack dirt..loose rock and RED Mud riding but that is just at the Mine where I work. Most is all Pavement riding with some straight Distance work too. Just ordered the Acerbis 3.1 Tank from Brian here at the Thumper store. Could not have been More helpful. Since I was ordering on my cell Phone from Vietnam he even Called me back on their dime to take our time and get the Order right..with Locking cap too. I will be getting the Bark Busters he recommended for BIG hands like mine and I higher Seat and plenty other options. I am happy to get any helpful Tips from all of you WR 450 Wizards out there. Normally I have to Fly to Bangkok in order to get any parts for my WR 250X but hope to do more online shopping here thanks to Brian. Exhaust recommendations are also welcome..I KNOW...I will be going through the forums.... ; ) I just want it a Little quite then my Akropooper on my 250x...The Local Villagers where I work just do not like it..or they are jealous.... Thanks in Advance for all your help..and for those that have the Smart ass remarks or answers....well..we all know what Kind of Mama You have..or Had ; ) WR Flano.
