Forum: Stunt Project Stuff Topic: Derbi GP1 Revolution SWindler Stunt - 172 cc ---------------------------------------------------- Waynder: Oke... After Cops took my SR 172 Stunter i decided to make a new stunt scooter that will be used to promote StuntBase and to win this years Hockenheim stunt competition =) For that i needed something very exsclusive, some model that no one uses for stunt and yet that it has perfect handling, brakes and chasis. thats why i choosed Derbi GP1 50 Revolution... Has rear forks, so no more busted selen blocks, has stock radial calipers, and has central rear shock absorder... But the problem is that its 50 cc and im a big fan of 172 2 stroke AC engine ;) So here we go... ENGINE RELATED STUFF 1. Original 50 cc Piaggio will be replaced with Aprilia SR 150 engine. this engine will be tuned with Malossi 172 cylinder and multivar 2000. NON ENGINE RELATED STUFF 1. 12 bar 2. sliders 3. green paintjob and black stickers 4. downhill steering 5. foot brake 6. oversize (if i find something good) ------------------------------- ------------------------------- 23.06.2007. Have started to dismantle scoot and tried to fit new engine on it... It doesnt goes there original so it will be needed to chage downer chaisis and rear engine holders... But not much problem if you know what ur doing... ------------------------------- ------------------------------- 01.07.2007. Ok... So the engine is fitted, chaisis is modded... Now i need to think a way how to solve the exhaust problem... If i wont be able to it stock one (will have to be cutted of course) i'll make new one tht will be undertail =) ------------------------------- ------------------------------- 27.09.2007. First test ride... Just to see about expected engine vibrations.. Everything went perfect ;) http://www.youtube.com/watch?v=cBY-QWnp2oQ ------------------------------- ------------------------------- 30.09.2007. Made first stage of 12 bar today. Thing is a bit complicated to be made on Derbi. It needs a lot of work and thinking to make it look both goodlookin and solid. Here is only 1st stage version without reinforcemant. Also this time i will use TITANIUM plates for those white sparks ;) ------------------------------- ------------------------------- 03.10.2007. Finally dismanteld whole thing and its all ready for powder coating... And yeah... It has Benelli chaisis =) ------------------------------- ------------------------------- 06.10.2007. Today camed chaisis from powder coating and rims from painting... So i started to put everything together... ------------------------------- ------------------------------- 13.10.2007. Building it up a bit... ------------------------------- ------------------------------- 22.07.2008. Long time no update... Well, i finally got some parts to make front end complete... Yes, it will use KTM SuperDuke farings and digits ;) This is just a fit on preview, will look much better in finish... ------------------------------- ------------------------------- 08.09.2008. Piece by piece im getting it together... 91% of job is done... Needs some more electric work with KTM digits, powder coating on all AL parts, custom bodywork... ------------------------------- ------------------------------- 09.10.2008. Had a big problem with wiring harness, so basicly we decided to make our own... Have cut out all the wires and gagets that i dont wanna use or i dont need and than started to make component by component... KTM digits are fully functional now... Has active all stuff to make it street legal... Still missing some farings, paint job and powder coating to make its design complete... After that there will be upgrading in susspension (breaks and rear suspension), transmission power up (stronger sprockets and chain) and maybe some setting around gearing... But bike is driveable the way it is now ;) ------------------------------- ------------------------------- 30.10.2008. I finally powder coated those parts... Also painted fromt faring... SO this is how it looks now... Beni: I cant wait.This will be a dangerous stunt toy. Good luck. Aerox_Jonne: are the cops allowed to take scoots in croatia?:shock: nice project btw, but isnīt the GP1 pretty heavy? Waynder: Aerox_Jonne wrote (View Post): › docWrite("quote")are the cops allowed to take scoots in croatia?:shock: nice project btw, but isnīt the GP1 pretty heavy? yup they are...but not cuz it was tuned... its a long story ;) anyways... derbi is a bit heavy yes... but it has incredible way of doing stoppies on any surface..and wheelies are much nicer cuz of rear fork thingy... besides... people stunt with 250 kg oldR bikes =)) brutale: good luck buddy on this uniqe project :) hardugo: Waynder wrote (View Post): › docWrite("quote")Aerox_Jonne wrote (View Post): › docWrite("quote")are the cops allowed to take scoots in croatia?:shock: nice project btw, but isnīt the GP1 pretty heavy? yup they are...but not cuz it was tuned... its a long story ;) well, if itīs not a problem for you, iīd really like to hear this story:)PLEASE!!!!^^ KicHo: nice one...can't wait to see it when it'l be finished...

Waynder: yup Waynder: here... Derbi today killed his 1st tyre =) Doich_86: Waynder wrote (View Post): › docWrite("quote")here... Derbi today killed his 1st tyre =) When will e see the video??? :wink: Waynder: Yeah there is a video... but its not very interesting... just brutal burnout while standing.. and a bit after the tire poped =) ANyway... i installed new tire... a bit bigger =) I think that i cant put anything bigger lol didl: the bike is just beautiful, tell me something,if you put bigger sprocket on this devil,will it have the same effect like on "big" bikes... :?::?: Waynder: yes it will... but i put the smallest sprocket that i could made on rear and biggest possible on front... also transmission has malossi 2nd... and scoot is still extra jumpie...and has end speed about only 100 kmh.,... perfect for stunting... but as i said... still is a bit too jumpie... so im looking for polini primar.... Myso_ST: Nice scooter Waynder...Do you have any picture of front end? Waynder: Myso_ST wrote (View Post): › docWrite("quote")Nice scooter Waynder...Do you have any picture of front end? this is how it looks now... by the end of the weeke will get a preety big upgrade on front end... Myso_ST: really great derbi...I cant wait to see how you stunt with him ;-) sh1z[SS]: <3 this derbi :) RideRR: Waynder wrote (View Post): › docWrite("quote")here... Derbi today killed his 1st tyre =) On ztz are some leftouts of a tyre. So much that you can make one tyre of it LOL. I guess that was you waynder playng with derbi =) . Derbi is crazy but i dont like the headlight of a duke. Somehow it doesent match ... Other things =perfect. From side it look too brutal =)) Waynder: Well... depandes on taste.. some people sid that looks perfect... BUt in future will probably change it with faring from SMR 690... Cuz SD faring is to big.. and when im doing wheelie i cant see over it lol... muhahaaa: You said earlyer, that this can make stoppies on any surfaces. I wonder how, cuz I tried with mine on rather good asphalt and gripping was poor. What kind of a tyre do you have in the front? Or is the secret in the way of braking or the postition? Waynder: ieven got rolling endo of about 12-15m on totally wet asphalt... tiers?Stock.... how to do it? its all in the "feeling"... just need to go few times "over" to find right balance... there is also much into body movment... needs right timing when you lift the scooter with ur ass.... its rather hard to explain, but its preety much simple when you get it workin... firefox_stunter: Waynder it's great scoot,nice job Owt Mike: its the coolest stunt project ive ver seen. Waynder: i know =D
