Suspension upgrades

Hey y'all, I need some answers. I'm planning out an expense plan to upgrade my suspension on my 2001 12 and I'm relatively new to bikes so I have no clue what to search for when it comes to compatibility upgrades.

I am looking for brake calipers, discs, rear shock upgrades that I can more or less just swap out and go. However I do know there are very limited bolt on options for my year bike so I'm taking everything with a grain of salt. So if anyone has got some good upgrades or threads I can look into that would be great.

Thanks guys
Vick

For a rear shock HyperPro sells plug and play shocks for a ZX-12.

Or a complete kit if you want to do front suspension too.

About the brakes... Nissin 4 piston calipers with Sinter pads and a Nissin Radial master cylinder - Works really nice. I also run Brembo rotors. Want more "bling" go with a Brembo master cylinder. The brake feel is progressive. For the rear, just rebuild the rear caliper, you find parts for a rebuild on Ebay.

Then the suspension... What is your budget and what are your plans for the bike? And ask yourself and answer truthfully if you are ready to spend a quite high amount of money on an old bike... The money you will have spent on brake and suspension upgrades will amount up to what you would have payed (total) for a newer sport bike that already has everything the ZX12R does not... and even after the upgrades it will NOT be a racer/track bike... I dont care what any one says... Yes it will stop and go around corners better, but still its not a match for a new sports bike.. BUT if you want a fun bike to ride around twisty roads, then that is a compleatly different story, then its, well might be worth it.

any way... I have done upgrades to my bike. Did the brakes first. Bought race cartridges (SD25 F4) from a company named Maxton Suspension located in the UK. I did the swap/rebuild myself, its not that complicated. Bought a rear shock from Wilbers, a Wilbers 643. Bike is actually really good now for what it is, soon 20 year old bike. Even done a trackday with it. Problem with the trackday I did was that that track was really short, tight and technical, not a good track for the ZX12R even with the upgrades, a faster flowing track would suit it much better...

Would I do it again.. Probably not.. specially after I rode my buddys 2016 Aprilia RSV4, that bike and how it handles is just amazing.. and you can find an RSV4 for a bargain today... another buddy asked me if I wanted to ride his BMW S1000RR and I said -No.. It would have only made me sad because it would have also handled so much better than my ZX12R.... So.. if you want a great handling bike, well its a tought choise, upgrade and old heavy dinosaur or save your money and buy a newer sport bike...

Thats just it, there arent any really.. Well you do have the ZZR1400... then again they dont really make bikes like this any more.. They are a dying breed... Kinda weird really because (my oppinion) adventure bikes just look dumb with the big boxes and most sport bikes are not as comfortable on long trips... and I dont want to ride a "BusaBrou"... If one is to belive the hype and everything that has been written, the best allarounder bike today is the BMW S1000RR.. Dont know if I personally think that, but many who claim to know say that, so...

But to answer your question... ALL mid- and higher end modern bikes do everything better (well not top speed) than the stock ZX12R... IF I was the ruler of the Universe, Id make Kawasaki and BMW build a hybrid/basterd bike with the A1 ZX12R looks, but the chassies, suspension and computer tech from a BMW S1000RR.. Now that would be the ultimate bike - PERIOD!!!
