Brand new px125 tuning

Hi all, Have just brought a brand spanking new px125 and am looking to kit it up. It to be used for commuting (40 mile round trip) and rallies. Ideally like to get about 70 mph out of the bike to match my old standard T5 (sadly missed). Am looking at a DR 177 kit, 24 carb and either a sito plus or stainless exhaust. Really don't fancy getting it ported etc. Do you think this setup would be fine or would anyone suggest other setups???

                                        Cheers in advance
