CBR1000RR 2008 -13, forks NSR/NC wheel conversion kit

CBR1000RR 2008-13 Forks, Wheel, Caliper, Disc Conversion Kit

This kit consists of the required parts to allow the standard NSR250, NC30/35 (many Honda) front wheel, 310mm diameter with 15mm offset discs (RC30 OEM discs for example) to be used together with the ’08- model CBR1000RR forks

TPER-0121  CBR1000RR 2008-13 Forks, NSR/NC Wheel, Conversion Kit

This kit consists of the required parts to allow the standard NSR250, NC30/35 (many Honda) front wheel to be used together with the ’08-’13* model CBR1000RR forks

Note that this kit is for the wheel only and does not take into account your choice of discs and calipers.

The standard CBR1000RR axle shaft cannot be used with the above mentioned wheels due to the diameter not being compatible with the bearing sizes in the NSR/NC wheel, so we have provided a shaft in the set that fits perfectly with the NSR/NC wheel.

Firstly, the design of the axle spacers allows them to stay attached to the wheel when the wheel is out of the bike, allowing easier fitting/removing of the wheel. To fit the spacers to the wheel you’ll see a lip on the spacer that locates behind the seal. Be careful not to damage the seal during fitting (use light grease) and now the spacers will stay in place.

The Fork Bush L. is fitted to the left hand fork from the outside, with the split lining up with the split in the pinch of the fork leg. This is to take up the difference in diameter between the axle shaft supplied and the fork leg bore

Please see drawing for how the axle spacers and fork bush are fitted.

TPER-0122  CBR1000RR 2008-13 Forks, Caliper Re-location for 310mm Discs, Conversion Kit

For this CBR1000RR 2008-13* Fork conversion, we used 310mm discs.

The original CBR1000RR 2008 setup uses 320mm discs, and small spacers between the caliper mounts on the forks and the calipers.

For use with 310mm discs these spacers must be removed, and replaced with our TPER-0121A dowels, which locate the calipers onto the mounts. This relocation means that the original 10x62mm caliper bolts are too long and should be replaced with the 57mm long bolts supplied.

TPER-0123  CBR1000RR 2008-13 Forks, Set, Disc Spacer

The typical fitted pitch of the discs on models such as NSR250, NC30/35 and many other Hondas is 130mm. This is also the case with 310mm RC30 discs that we used. However, this conversion requires a pitch of 133mm, so we provide TYLY-0121C 1.5mm shims to offset the discs on each side by the correct amount to centre the disc rotors in the CBR1000RR calipers.

The RC30 discs are a nice choice and have a 15mm offset measured from the clamping face to the centre line of the rotor.

The Honda OEM discs have a small issue on the right side, as the back side of the mounting face of the disc has a large chamfer which means that there is very little surface to locate on the cylindrical part of the wheel. we found that aftermarket 310mm discs do not have this large chamfer and therefore locate securely, and possibly a better choice.

* Disclaimer: We are not exactly sure of all the years that this conversion works but it should be ok for the model years 2008-2013.
