Is the Pulsar N125 a good platform for customization?

Modding has always been strong with the Pulsar series, but how does the N125 stack up in this regard? There are some riders who love to personalize their ride for performance gains, better looks or improved comfort. However, with the N125 being an entry level model, are there enough aftermarket parts out there? What about the warranty implications of modifications? The question is also there, whether modding a 125cc makes sense when you can just upgrade to a higher displacement bike? On the other hand, mods may be more beneficial to a lighter bike. I'd love to hear from riders who have customized their N125s, what worked, what didn't and was it worth the effort and expense?
