This throbbing 300cc KTM engine conversion is a finely engineered and crafted bit of kit, and has that special Midas Touch.

Trevor Harrison is no stranger to the scootering scene. The passion is in his veins and Trev’s antecedents speak for themselves.

Trev has been involved in the production of some fantastic custom scooters over the years. To mention just a few: Anthony Miller’s Lambretta, ‘Beyond Redemption’; Gary Carr’s Lambretta Vega, ‘Murder’; Roob Harker’s Lambretta, ‘Split Personality’; and Paul Muirhead’s Lambretta Chopper, ‘Dead Man’s Shoes.’ The list continues, and to add to Trev’s already impressive credentials he also still jointly holds the ACU official quartermile record. So what’s the point of all the preamble you may ask? Well, it’s simple. Trev’ now brings us his own custom KTM-inspired Street – Racer Lambretta, ‘Extreme’, which is a giant slayer, based on humble Lambretta underpinnings. As we alluded to earlier, Trev’s an experienced scooterist who has accumulated a vast amount of knowledge, connections and experience over the years, which he’s playing to his advantage. The experience Trev has gathered over the years has allowed him to choose a blend of technology, engineering and a team of specialists who’ve put together an absolutely awesome scooter, which in the hands of the inexperienced would come with a health warning. But in the hands of an experienced scooterist like Trev it makes you look like a champion. The scooter oozes a single-minded attitude to performance, style and technology.

Engine choice

‘Extreme’ is a fast scooter, and there’s a good reason for that as it’s based around a KTM engine. KTM has produced a solid reputation for building some of the best off-road bikes on the market with the engineering to suit. One of their most desirable engines is the KTM 300 EXC, which is the one Trev chose for his scooter. Hearing the engine crackle to life is amazing, it accelerates like *!!%** and seeing it in action makes you take a deep breath. The engine is light and powerful, and KTM claim the bike which it comes from has the best power-to-weight ratio in its class. So how did all this start? “A pal of mine, Jason Potter, from York, had a YZ250 engine fitted in his Lambretta. I had a Lambretta, which was running on a 240 engine and was kicking out around 30bhp,” Trev explained. “To give Jason a run-for-his-money I decided I’d chase him on my scooter, but in doing so I put a hole in my piston! Of course this gave Jason the opportunity to start taking the Mickey, which motivated me to think: ‘I’ll show you, I’ll have the last laugh! And my ideas for ‘Extreme’ were born.”
