Later model forks - early F4

I found some corrosion on my forks where the mudguard collects water against the fork legs so decided to replace my forks.

Found what I thought would be a nice sensitive upgrade with what I thought were later model forks with radial brakes, but the wheel spindle is much smaller on the new forks.

Can I replace the spindle in the wheel or is that not an option?

Cheers

Which model F4 have you got ? There's several threads discussing the two axle sizes on the pre-2010 bikes, as well as the spacers used to accommodate the axle differences.

Mine's an early 200my 750 with a large spindle.

The later model forks are much smaller so I'm assuming a spindle and wheel bearings will suffice or is there a difference in the wheel?

I searched for 'wheel spindle' so I'll have a look for axle size.

even though it seems simple to just change the bearings you will find the bearings needed for the 25mm spindle have a smaller outside diameter than the older bearings and will not fit the wheel from the older bike. You may have to buy a newer wheel to make it all work. You will also need bigger brake disc

I'm hoping to be able to source a bearing with the inner radius to match the 25mm spindle and outer radius to match the wheel.

Hopefully these chaps will have something suitable:

No man, all the info you need is in this thread - it's up to you to know your bike, the parts you bought, and to sort through the rest http://www.mvagusta.net/forum/21-per...-they-fit.html
