This conversion kit includes the parts you need to convert the complete USD front end from a Honda RS250 NF5/NX5/NA5 to fit the NSR250 MC21/28.
Top Clamp Collar
Top Nut (TYLY-0027)
Steering Stopper bushes and bolts
To fit the parts you will need to press the RS stem out of the RS lower clamp. Remove the clip from the bottom of the RS shaft and re-fit this to the conversion shaft. Then press back into the RS lower clamp.
The top clamp collar is a press fit into the top clamp, from the top side. this resizes the top clamp to fit the conversion shaft.
Headstock bearings are OEM NSR items, or TYGA taper roller. These must be purchased separately.
The final attack is fitting the steering stoppers. To locate these, loosly fit the converted headstock to the NSR and then turn your steering to left and right, marking the location of the steering stopper positions to give you just enough clearance for no interference with radiator etc. Check and double check position, then drill (dia. 6.8mm) and tap to M8. Use the supplied M8 bolts to secure.
You can now fit the rest of your front end with ease.
