I rode a Honda VFR800 VTEC when they first came out and was singularly unimpressed with it, feeling that they'd totally spoilt a very good bike (the VFR800 Fi). Suzuki's latest GSXR1000 has VVT and by all accounts benefits from much better low and mid range torque from having it. Quite what the benefit on a big V twin remains to be seen as they are not known for lacking low end torque in the first place. So it will be interesting to see whether it really does benefit or is just a marketing exercise. The other downside to Honda's VFR800 VTEC are the servicing costs. Whether this will also be the case on the Suzuki remains to be seen.
