Jigged Belt Drive Trike Conversion Kit

The Casarva Harley Davidson Sportster Jigged DIY Belt Drive Kit is like all our conversions and is built in British steel tube with a 2.64mm wall. It features sealed bearings and is mated to a Casarva differential (BMW planet gears). We will require your rear pulley to mount to the differential. If you wish we can supply a replacement pulley at additional cost.

Once the bikes back end has been stripped off, you can have your Sportster trike as a rolling trike within hours!

This kit is specially for the Hard Mounted engine version of the Sportster. Because the mounting tubes have been welded in place by Casarva, you can be confident it has been done correctly and will give your trike that “Works Build” look.

***For a rubber mounted engine please contact us as you will most likely require a new rear engine rubber mounting which become deformed on the bike for the kit to fit ***

Furthermore if you bring your trike to the Casarva Works in Peterborough, we will inspect it and if you have fitted it properly we will endorse the trike as Casarva Quality.

In our experience Casarva Works built trikes have a higher resale value than home built and our endorsement will mean your trike is of the same quality of build – which will also give you peace of mind all for just £75 + VAT!

Wing carriers can be pre-formed to your choice of mudguard only if the wheels and tyres for the trike and wheel hubs are with us at the works
