Most conventional bicycle wheels now use 32 or 36 spokes front and rear, although the asymmetry of the rear wheel (to allow for the cluster of sprockets), and the additional weight it carries, means it benefits from having more spokes than the front.
The Steffey motorcycle in 1902, essentially a bicycle with a two-stroke engine attached, used wooden, rims with wire spokes. [1] This style of wheel evolved into a stouter motorcycle-specific wheel, still with spokes, up to the 1960s and beyond. [2]: 134 In April, 1922, Borrani started production of motorcycle wheels with an aluminium rim. [3]
Shallow-depth, hook bead, carbon spokes, and no outrageous price tag for this tubeless-ready wheelset. Hunt 32 Aerodynamicist UD carbon spoke wheels are ultra-light, not ultra-pricey Skip to main ...
What metal the spokes were made from depended on the model of motorcycle. The CB400T, for example, used steel for the spokes and alloy for the rim, whilst the CBX and the Super Dream used alloy for both the spokes and rims to further reduce unsprung mass. For the NR500, the wheels were made from magnesium, with titanium used for the fasteners ...
For example, a 32 spoke wheel has 16 spokes per side, 360° divided by 16 equals 22.5°. Multiply 22.5° ("angle between adjacent flange holes") by the number of crossings to get the angle a—if 3-crosses, the 32 spoke wheel has an angle a of 67.5°.
Wide Excel 17 inch chromed steel (36 spoke) rims are laced with thick 4.4 mm spokes to silver painted aluminum alloy hubs, necessitating the use of tube-type tires. The front brakes of the GT1000 were derived from the other SportClassic models, and had two Brembo floating calipers with 30 and 32 mm diameter thermally insulated pistons.
The Supersport 1000 DS had a pair of Brembo Gold Series callipers with 320 mm discs at the front and a single 245 mm disc at the rear, along with lightweight 5-spoke Marchesini wheels. The Supersport 1000 DS produced 95.2 N⋅m (70 lb⋅ft) of torque at 5750 rpm, and 95 hp (70 kW) of power at 7750 rpm.
A working prototype of a centreless wheel, using ball bearings, was shown at India Bike Week 2014 in Goa. Attached to a customized Royal Enfield motorcycle, the prototype rear wheel was designed by a team by the name of Freedom Sprints, which included Abhishek Sharma, Ankur Tiwari, Sarvesh Khemka, Yashodeep Yadav, and Mohammed Ansar.
