|Tire Options & Info for RSV|

This is a listing of tires and their specifications available from most major manufacturers in sizes to fit the Royal Star Venture. The information was compiled to provide a one-stop comparison of what is available. All data was gathered from the manufacturer's websites and brochures. While every effort was made to insure accuracy of the data, due to the possibility of typographical errors in the source documents or here, you should verify all info with your tire dealer before ordering to insure you get what you want.
The OE tire sizes for the Royal Star Venture 1999 - 2007 are:
The OE Brands and models used are the Dunlop D404 or the Bridgestone Exedra G series.
Some riders have installed an MT90B16 (equal to 130/90-16) tire on the front of the Venture and have reported more stability at parking lot speeds and better handling in the curves and on the open road at highway speeds. Yamaha does not recommend any sizes other than the OE sizes for use on the Venture. Some shops will not install a non-OE sized tire, so you may want to consider this before making the change. However, due to the large number of riders who have made this change and raved about the improvement in handling, including myself, I have included the MT90B16 tires in this list for those inclined to try them. Do so at your own risk.
Always run a matched set of tires for best performance and safety. Mis-matched tires may have different handling characteristics which could upset the motorcycle under certain conditions. After installing new tires, allow a 100 mile break-in period to become accustomed to the feel of the new tires and to scuff them in. Check the tire pressure and condition regularly, preferably before every ride. Adjust the pressures to accomodate the load on the bike but never exceed the maximum pressure listed on the sidewall. Check and adjust air pressure while tires are cold as heat will skew the readings.
SW = Sidewall, BW = Black Wall, WW = White Wall, WWW = Wide White Wall, NWW = Narrow White Wall, RWL = Raised White Letters
* Non-OE Tire Size
** Caution! The 130/90-16 Shinko Front 675lb load capacity is 86 lbs less than the OE tire specs. It is NOT recommended to use tires with a lower load capacity than the OE tires!
** Continental website and technical manual claims this CM2 rear tire can be fitted to the front on the RSV. Verify with tire dealer. The 150/80-16 is not made in the CM1 Front version.
Speed Rating = The maximum speed a tire can sustain under it's recommended load capacity. The speed rating is listed on the sidewall near the tire size, next to the load index. Example: 77H
Load Index = The maximum load capacity of the tire at it's maximum inflation pressure. The load index is listed on the sidewall near the size and right next to the speed rating. Example: 77H
What the numbers and letters in a tire's size mean.
Motorcycle tires are built in both bias ply and radial ply construction. The Venture and it's rims are designed and built to use bias ply tires only. Radial tires are not recommended for use on the Venture or it's rims. However, many people wonder what the differences are in the two types of tires.
Bias Ply tires are constructed with plys that run diagonally from bead to bead and alternate directions from one ply to the next. The number of plys may vary depending on the load capacity of the tire. Bias ply tires may or may not also be belted. Belted tires have an additional ply, or belt, that runs around the diameter of the tire under the tread for additional strength and stability.
Radial tires have plys that run radially, or straight across, from bead to bead. Radials also have belts that run around the diameter of the tire under the tread area to help stabilize the tread for better handling. Radial sidewalls are more flexible than bias ply tires and have much different handling characteristics. Radial tires will have an "R" in the size, usually right after the aspect ratio, that indicates it is a radial tire.
The plys are a layer of threads made from a cloth-like material such as rayon, nylon, or aramid that are bonded in rubber. Belts are usually made from a stronger material such as kevlar.
Motorcycle tires are directional!
Tread wear indicators are small lines or raised areas in the tread grooves. When the tread is worn down even with the indicators it is time to replace the tire. Some tires have small triangle symbols on the sidewall near the tread to show where the tread wear indicators are located.
Are your tires fresh?
All tires sold in the USA have a DOT number on the side wall. At the end of the DOT number is a 4 digit date code with the first two digits indicating the week and the last two the year the tire was manufactured. The tire in the picture below was manufactured the 27th week of 2004. Tires built before the year 2000 used a 3 digit date code with the first two digits indicating the week and the last digit the year of manufacture. Hopefully, you aren't running any tires old enough to have the 3 digit code on your bike. Depending on how they were stored, tires as little as four years old could be dry rotted enough to be considered unsafe to use. Don't risk your life trying to save a dollar. If there is any doubt about the condition of your tires, have them inspected by a professional or replace them. Remember, your tires are the only thing between you and the road.
