dry sump oil system with the oil tank inside the gearbox case.electronic control unit with 3-D ignition maps for each cylinder.rocker arms with screw-and-locknut clearance adjusters.cylinder heads with two intake valves and a single, larger, exhaust valve.In addition to the 52° V-twin layout, commonalities for the 18 powertrains include: The VTX1300 line was introduced for the 2003 model year, which evolved into the VT1300C line starting with the 2010 model year. Nevertheless, the VTX 1800 still produced better 0-60 mph and 1/4 mile times.

At the time this bike was introduced the Honda VTX engine was the largest displacement production V-twin in the world, but that distinction would be short-lived as the VTX1800 was superseded in 2004 by the 2.0-litre Kawasaki Vulcan 2000. The Honda VTX 1800 was launched in 1999 as a 2000 model. The Honda VTX series is a line of V-twin Honda cruiser motorcycles inspired by the Zodia concept shown at the 1995 Tokyo Motor Show. R: Swingarm, dual shocks with adjustable preload,į: Dual discs with LBS, three-piston calipers I expect to use a slightly stiffer compression/rebound setting over the standard settings. I am about 100kg and will put in a 22.7 over the weekend. You need to check the manufacturers' data sheets to be sure not to get oranges instead of apples. Will that increase your damping? NO! The 10W from Castrol has only 15.00 To make matters even more complicated, the Castrol Synthetic Fork Oil 5W has 28 and in 10W it is 42.00 The 7.5W Motorex Racing Fork Oil has 35.9 while the 10W Silikolene Fork Oil has 34.90 are a couple charts listing a bunch of fork oils and their Let's say you replace it with 10W from Castrol. If you want a apple-to-apple comparison you need to look at the viscositiy the oil has at 40☌ SUZUKI FORK OIL L01 (the one recommended in the Workshop Manual) has 15.50 As was suggested here, it is a 5W oil. Unlike motor oil, there is no viscosity standard for fork oil.
