Re: Larger rear tire.

Update: Back from the air show. Only rode 155 miles in 1 and 2nd gear this year. poor weather the first 3 days limited aircraft arrivals, but last 3 days were perfect. Enough of the airshow, so how did the 130/90-16 front and the 140/90-15 work out? The only thing I can say not described above is 1: raise the front fender 1" higher (or more if you want) as the 3/4" I used is minimal and 2: above 40 mph the bike seems to be more stable, probably due to the greater weight and diameter of the tires giving more gyroscopic forces to the wheels. 3: riding up the raised sides of the taxi ways almost on a paralell coarse ( a 2" to 4" drop/rise) caused no problems. The D404 dunlop tires smoothly rode up onto and off the pavement into the grass with no side pull or any kind of jerk, just a steady ride. The rain soaked grass fields with grass and standing water were no problem to ride through. If you stopped the rims sank into the grassy sandy mud up to the rim/spoke level, much more stable if speed was kept at 10 mph or greater. The wider fat tires seemed to stay on top of the wet grass/mud better and just puched right through at 10 - 15 mph. I may post a fender "how to raise higher" 130mm tire install in the "how to" section in the next week as a seperate topic. --Dan--
