TBI vs TPI! Riding my 2023 KTM 300XC with Throttle Body Injection (TBI) and my 2021 KTM 300XCW Erzberg with Transfer Port Injection (TPI) back to back to talk about the differences between TBI and TPI and what stands out.

2021 KTM 300 Erzberg:
The 300 TPI engine on my 2021 KTM 300 Erzberg has smooth linear power that has run perfectly for me from 11F to 95F temperatures. I like oil injection for the gas and go simplicity. The TPI 300 engine has very smooth roll on torque (which some riders complain is too smooth) with less peak power and a little flatter feel up top compared to TBI. The PDS chassis feels smaller and has quicker steering than the newer linkage chassis on the '23 300XC. Still a very fun bike on the trails.

2023 KTM 300XC:
The '23 300XC TBI engine is powerful! The low to mid partial throttle roll on torque feels much stronger on the TBI engine with a more classic carb like meaty power feel. There is also a noticeable difference between Map 1 and Map 2 on the 300XC. Map 1 (stock) is a little smoother response while Map 2 (aggressive) has stronger throttle response with a little longer pull way up top. The chassis on the '23 300XC feels firmer and bigger (better ergos for taller riders...I am 6' 2" 190 lbs).

While both engines are 300cc fuel injected 2-strokes they feel different. The 300 TPI is less powerful overall with a smoother roll on power feel. Perhaps better for the off road woods riders. The 300 TBI feels like it makes 3~4 more peak HP and has more meaty and stronger low to mid throttle torque feel and Map 2 is very responsive. Perhaps better for more open style off road and moto riding. Both are very good engines. Nice to have choices!
