# Big Twin.. 5 Speed 86 - 99 Trans 24T sprocket + 48T rear + 120 Link Heavy Duty Chain
22mm from inner to outer face ( should be good for 150 tire use ) comes with rear sprocket spacer.
If required.... we have a seperate listing for new sprocket nut ( NOT included in this listing ) as well as a listing for a high tensile Allan cap screw ( which is now included ) for locking the sprocket nut in place.....see photo below to show installed position... although it is on another model type sprocket.
As i do not have the full information to supply a kit that will 100% fit straight away, best start with our basic kit. As there are so many model variables and customer individual requirements, you may need other parts to complete the installation. Treat this as a starter kit, to offer up to see what you may or may not need, we will work with you to finish the job, by excepting parts back ( Sorry NO refunds on postage are given )and supplying spacers or other sprocket combinations as required. Also great for working out what you will need to clear for wider tire use.
Or start by just by buying / using a rear sprocket….. to enable you to work out your front sprocket width required, by measuring with a straight edge onto your outer face of a ( old / borrowed or new from our listings ) rear sprocket, already fitted on your wheel ( spaced to allow clearance for your chain to tire ) centered and squared in your frame. Measure the distance from the same edge in contact with the rear sprocket outer face, to the exposed main shaft bearing spacer.
