I have a Kenevo and made 3 modifications/upgrades that changed the bike for me are:
- Minions front and rear (personally think the spesh tyres are meh)
- Tubeless is essential (noted you already have that)
- Aftermarket brake pads (personally think stock pads from all brands are average at best)
In my very early days of riding I was given some great advice to always have the contact points suited for you (grips, pedals, saddle) so I always change grips and pedals as a personal preference although that isn't a performance mod per say but the 3 mods above have been done on my bikes for years (unless the rubber is maxxis to start with) and afterwards it has made a noticeable difference.
