SCOOTER DETAILS

Name of scooter: Klappstuhl (‘folding chair’ – meaning unstable ride in German) Model: Vespa PX Inspiration for project: Wanted something uncomfortable, noisy, lowered, fast but TÜV approved. Time to build: Frame modified by my mate Dietmar. Took me six month to complete. Frame mods: Legshield cut, fork shortened in two places, mount for top steering race cut and welded on lowered steering column, tank shortened and seat embedded in frame, PX legshield toolbox cut and welded. Engine panel shortened, louvres and holes cut into it. Spare wheel panel shortened and closed at bottom. Tunnels in bodywork for LED rear light and LED indicators by Paaschburg & Wunderlich (www.pwonline.de). Cut out in front of seat, lobe behind seat cut from sheet metal and welded on. Specialised parts: Fully hydraulic front disc brake with Grimeca master cylinder, fully hydraulic rear disc brake by Scooter Attack, Braided steel brake lines by Spiegler, rear brake pedal with master cylinder by MMW, one-off wiring loom by owner, self-made seat made of wooden board with foam mat covered with synthetic leather, self-laminated fibreglass belly pan, Acewell digital speedo (TÜV approved), quick action throttle, Pro Grip grips, preload adjustable YSS shock absorbers for Vespa PX at rear and Piaggio Zip at front. Engine: Malossi 210 barrel, ported auxiliary port, modified piston, MMW 2 reed cage, Tassinari VForce 3 reed block, 30mm Mikuni power jet carb with Mikuni vacuum pump, BGM Superstrong clutch, right hand JL pipe with exhaust tape, ‘Glockenwelle’ crankshaft (i.e. webs machined into bell shape) using DRT big end pin giving 62.5mm stroke, standard reprofiled cylinder head, standard ignition system. Dyno power output: 30hp at wheel (all work done by owner). Top & cruising speed: Cruising 65mph & top 80+ mph – needless to say it’s completely unrideable at that speed! Is the scooter reliable: Yes! Paintwork: Completed by Dietmar’s mate. Overall cost: Over €5000. Hardest part of the project: Not to cut it down even more… Advice for anyone starting a project: If you’d like to ride a street legal scooter in Germany make sure you find a friendly TÜV engineer and build/modify everything to his recommendation. That gives you the best chance to get the modifications entered into your log book, i.e. legalised. Favourite dealer: Scooter Center Cologne and small dealers/manufacturers from German Scooter Forum offering specialised parts. Thanks: To Dietmar O.
