Does anyone know if any other model front wheels fit straight on without messing with spacers etc?

It's to help me source one on eBay. Thanks.

 

VFR400's (NC30) front rim is 100% identical. SC28 and SC33 Fireblades front rims will also fit, but they are only 16". Some VTR's front rims are also suitable, but 3-spokes.

Motorcycle Radiators | Motorcycle Exhausts | High Performance Motorcycle Exhaust Systems makes quite cheap 100% identical aftermarket rims.

 

Thanks.
Are these a straight replacement (VFR, VTR) or do they require different spacers, disks etc?

 

Those all are straight replacements. You don't need any spacers, different front discs or any other parts than a new rim.

Please note those specific models, SC28/33 (Fireblade) and NC30 (VTR) - I'm not sure about other years. Suitable VTR1000 rim's were from older ones, maybe '98 to '01 (or even to 2005?).

Some 1100XX Blackbird's rims would also match...
